Problem description:

Where can I find more information complete information on spawning mushroom cultivation techniques, including investment costs, suitable climate for growing spawning mushrooms, growth cycle of spawning mushrooms, where the seeds and associated technical assistance are supplied, the Is Sanshui region of Foshan also suitable for planting? have a market analysis.

Analysis:

Agaricus bisporus has the characteristics of excellent quality, good taste, low investment and high efficiency. It has broad market prospects. , with an economic profit of 12,000 yuan per 667 m2. Its cultivation technology:

1. Prepare cultivation materials and formula Based on a 100 m2 cultivation, you need to prepare 1,500 kg of high quality dry wheatlity. of straw, 600 kg of dry cow and horse manure, 50 kg of phosphate fertilizer, 15 kg of urea, 25 kg of gypsum powder and 12.5 kg of calcium carbonate.

2. Stacking and turning of cultivation material

(1) The whole process of stacking cultivation material takes about 25 days, and the pile construction time is carried out 5 days before sowing.

(2) Stack and turn. Cultivated material should be stacked in a place with flat ground, no water, no pollution and a water source; 2-3 days before building the pile, soak the wheat straw in water and remove it, sprinkle 1.5 layers of lime powder evenly. layer by layer, then stack the wheat straw into a pile. Make a large rectangular pile, layer by layer, and pre-wet the soil from horse manure at the same time when building the pile, first spread a layer of damp wheat straw on it; the stockyard, 15-20 cm thick, then ssprinkle a layer of manure on the wheat straw, a total of 10- For 12 layers, add an appropriate amount of water starting from the second layer, and turn the pile four times The first. the time is the seventh day after the construction of the pile. After that, each time is spaced 5-6 days apart. Each round strictly conforms to the technical requirements.

3. Sowing

(1) Sowing time: The outdoor temperature is around 25℃, and the material temperature is below 28℃. Depending on temperature conditions. of our city, September 5 is currently appropriate.

(2) Seeding rate: 500 g/bottle per m2.

4. Management after sowing and before covering with soil

(1) After sowing, the relative humidity should be maintained at about 80% if the material temperature exceeds 28°C and the temperature in the hangar exceeds 30°C, Adequate ventilation and cooling.

(2) Within 4 to 10 days after sowing,small ventilation should be carried out in time. If the humidity is around 70%, which is low, you can cover the surface of the material with paper. , then spray it with 1% lime water paper until the paper is damp but no water accumulates.

(3) Remove the paper in time 10 days after sowing. After 15-20 days, when the mycelium has practically filled the layer of material, it can be covered with soil.

5. Soil cover and post-cover management

(1) Soil cover: 2.5 m3 of soil is required for 100 m2. Mix 50 kg of phosphate fertilizer, 1-2 lime powder. , and water into the soil, grab it into a ball, scatter it and spread it evenly over the surface of the material, to a thickness of 2-2.5 cm.

(2) Management after covering with soil

1. Moisture: The moisture content of the covering soil layer is generally 20%. When the mushroom budsgnons turn into grains of rice, spray it and water it once.

2. Humidity: After covering with soil, the humidity of the space should be between 80 and 90%.

3. Temperature: The suitable temperature for mycelial growth is 13-18℃, and the suitable temperature for solid growth is 13-18℃.

4. Timely harvest: harvest diameter 2-4 cm.

Experts predict that the price of edible mushrooms in our province will continue to rise this year, but oyster mushrooms will gradually be replaced by shimeji mushrooms, oyster mushrooms and white mushrooms. This is mainly due to the quality of the mushrooms. Oyster mushrooms are in decline and their price could see a slight drop. Some edible mushrooms with good taste and high nutritional value, such as king oyster mushrooms, shimeji mushrooms, pleurotus pleurotus, white mushrooms andtea tree mushrooms will be very popular with consumers and their sales will certainly double compared to 2005, particularly Agaricus. bisporus. The market share will increase significantly and planting rare edible mushrooms will definitely give a good harvest. The current wholesale price of Agaricus bisporus is between 2.7 and 3.5 yuan/jin.

Do you know what old farmers often say: “Water three times and apply three fertilizers when growing vegetables”?

The key to vegetables growing well and having high yields is water and fertilizer. Watering and fertilizing are two essential steps in growing vegetables. However, the water and nutrient requirements of vegetables are not static from sowing to harvest. Reasonable watering and fertilization should be carried out according to the water and fertilizer requirements of different growing periods. However,most producers do not follow the rules. farmers do not follow the rules. Some beginning growers often let their vegetables go bad due to their own watering and fertilizing.

Therefore, if you want to grow vegetables well, the first step is to learn how to water and fertilize. Old farmers often say that when growing vegetables, you need to learn to water three times and apply three fertilizers? Do you know them ?

Dingmiao water refers to the water poured when planting vegetable seedlings. After the vegetable seedlings are planted, the soil layer around the rhizomes should be watered immediately and once. The goal is to promote close contact between the rhizomes and the soil, the second is to prevent the rhizomes and plants from drying out and the third is to promote growth and development.rapid development of rhizomes. Seedling water determination is important for survival after planting.

For vegetable plants whose rhizomes are not very prosperous, when pouring the root water, you can add an appropriate amount of root growth and seedling agent to the water . This will help the rhizome grow quickly and slow down. roots quickly and promotes early growth, but after slowing down the roots, there is no need to switch to a fertilizer for root growth. You can replace it with an organic inoculant or functional fertilizer for root growth.

So-called squatting water is water after vegetable plants have been planted and their roots have slowed down. When vegetable seedlings are planted and their roots are slowed, water should be cut off. and drained, which means less watering, simply make the layerslightly damp soil. Under normal circumstances, no sandy soil is visible in the top 2 cm of the soil layer. Its effect and function is to allow the roots of plants to develop. penetrate the deepest.

Since rhizomes have the ability to find water sources, when the soil is dry, the rhizomes automatically bend and stretch towards places where there is water. How can we form a more developed rhizome? become stronger and stronger, prepare for the futuredevelopment and performance.

During the growth period, vegetables not only need a lot of nutrients, but also need enough water, such as tomatoes, cucumbers, green beans, peppers, long beans, etc. The characteristic is that less water is used at the beginning of flowering and enough water is needed from the fruiting stage to the expansio stage.n of the fruit to meet the growth and expansion needs of the fruit, and it can also reduce the physiological falling of fruits. However, watering at this time should not be flooded, but should be watered slowly and frequently with small amounts of water. When watering, combined with fertilizing, the fruit will grow faster and stronger.

Basal fertilizer, also called basal fertilizer, is a chemical fertilizer used before or during planting. It is usually mixed into the soil when shoveling or applied when planting. the bottom of the rhizome. Basic fertilizer plays a key role in the overall growth and development of crops. This is a very important chemical fertilizer that must be applied well and in sufficient quantity, fermented organic fertilizers must be selected, such as: animals. manure, farm manure, rapeseed cake, etc. These fertilizers havehave a long fertile period and can continue to supply crops throughout the growing period, so they cannot be ignored.

Top dressing is a chemical fertilizer provided during the growth and development of crops. As crops continue to grow and develop, the nutrients they need gradually increase. of growth and development. At this point it is necessary to add additional fertilizer. Top dressing requires selecting different chemical fertilizers according to different crops and determining the frequency of top dressing based on growth rate and soil organic matter. Top dressing is different from basic fertilizer. Typically, soil is dug away from the rhizome around the roots, fertilizer is put into the mud, then smoothed with soil. Chemical fertilizers can be farm manure, manure waterfarm food, peanut bran, fast-acting fertilizers, etc.

Foliar fertilizer should be sprayed primarily on the foliage, because when vegetables grow and develop, the leaves also need to absorb nutrients. Spraying the foliage can compensate for digestion and absorption of nutrients. Roots. It can quickly replenish nutrients for crops, has the characteristics of rapid digestion and absorption, and saves costs.

Foliar spray fertilizers mainly use water-soluble amino acid fertilizers, because they contain various trace elements and have a certain healing effect on some yellow leaf diseases. Commonly used foliar fertilizers include: potassium dihydrogen phosphate, urea, amino acids, brassinoids, fluid boron, etc. Appropriate foliar fertilizers can bere selected and sprayed according to different crops, which can not only promote growth and increase yield, but also prevent leaf aging. and yellowing.
