How should you select mushroom spawn for high yields when cultivating Agaricus bisporus in paddy fields?
Give priority to granular wheat grain spawn with good yield performance and strong stress resistance, followed by manure-straw bag spawn. To plant 1 mu of field mushrooms, about 400 bottles of wheat grain spawn are needed, with an investment of 800-900 yuan; or 800-1000 bags of manure-straw bag spawn, with an investment of about 1000 yuan. Farmers should be especially reminded that when buying spawn, they must go to a spawn farm with a good reputation.

Do not make these mistakes when growing button mushrooms (Agaricus bisporus) in paddy fields for high yields
In actual production, farmers often make certain mistakes that affect the profitability of cultivation. First, insufficient pre-wetting. Rice straw must be fully soaked before it can decompose well. Straw that has not been soaked sufficiently needs a large amount of water added during turning, and if the water cannot be replenished before the second turning, it will be very difficult to make up later, which seriously affects the growth of mushroom mycelium. Second, uneven turning. It should be done according to the principle of "raw material in the middle, cooked material on both sides; the middle goes to the two ends, the two ends go to the middle." Some growers, when turn

Key Technical Points for Mushroom Cultivation and Management in Winter Fallow Fields
Using winter fallow fields to cultivate mushrooms with rice straw and manure as the main raw materials can greatly increase income, and the spent substrate after cultivation can be returned directly to the field or used as raw material for bio-organic fertilizer. The winter fallow field mushroom cultivation technique is introduced as follows: Substrate formula: when stacking materials, calculated per square meter of mushroom bed, use 12.5-13.5 kg of dry rice straw, 0.8 kg of rapeseed cake powder, 0.45 kg of gypsum powder, 0.45 kg of superphosphate, 0.45 kg of compound fertilizer, and 0.45 kg of lime powder. Per mu

Growing button mushrooms (Agaricus bisporus) in winter-fallow rice fields delivers good returns
In 2004, our county carried out cultivation demonstrations of growing button mushrooms (Agaricus bisporus) in winter-fallow rice fields across 16 townships. After the late rice harvest, rice straw and other materials were used as the main raw materials and composted and fermented into growing substrate, making use of the winter temperature and light resources and the idle winter season of the rice fields; open-field cultivation of button mushrooms achieved notable returns. Chen Yeru, a farmer at the Lixian Institute of Agricultural Sciences, is a button mushroom cultivation demonstration household, with a family of 4 people and 2 laborers, and had never previously cultivated edible fungi. After technical training at the Lixian Edible Fungi Research Institute, he set up on his own contracted field

How to Cultivate Mushrooms in Winter Fallow Fields? Detailed Technical Points
Using winter fallow fields to cultivate mushrooms is a good way to increase income. At the same time, it helps to build soil fertility and increase grain yields. The technical points are: 1. Material preparation. For every 100 sq m cultivated, prepare 1250 kg of rice straw, 1750 kg of cow manure, 45 kg of peanut bran (select well-composted), 15 kg of urea, 40 kg of lime, 25 kg of superphosphate, and 25 kg of gypsum. 2. Pile composting and fermentation. Generally, start piling the material 1 month before sowing, that is, around early October, and the composting period is about 1 month,

Plastic Film Mulch Cultivation Techniques for Potatoes in Winter Fallow Fields
When cultivating potatoes in winter fallow fields, if the plastic film mulch cultivation method is adopted, the potatoes can be brought to market earlier, thereby achieving higher economic returns. The key cultivation techniques are as follows: 1. Soil selection - Choose slightly acidic light sandy soil that is loose, well-aerated and well-drained for cultivation. Clayey soil is heavy, poorly aerated and drains badly, which is unfavorable for tuber development and unsuitable for growing potatoes. When using harvested late rice paddies to grow spring potatoes, be sure to choose raised fields and second-bank fields with loose soil and good drainage. Potato

Pest Control Methods and Key Technical Points for Panax notoginseng Seedling Fields
When aphids and scale insects cause damage, spray 50% phoxim emulsifiable concentrate at 1000 times dilution or 40% dimethoate emulsion at 1000 times dilution for control. In plots with a large number of white grubs and cutworms, apply 50-75 g of 90% trichlorfon crystals per mu mixed with 20 kg of fine soil and broadcast, or mix with 50 kg of chopped fresh vegetable leaves and broadcast in the evening. For rodents damaging Panax notoginseng gardens, based on their habit of hiding by day and coming out at night, block their burrows during the day and place rat traps, rat cages

Cultivation Methods and Technical Key Points for Intercropping Garlic in Cotton Fields
When garlic is intercropped in cotton fields, each mu can produce 93 kg of lint cotton and 1,300 kg of garlic, with a benefit of about 3,300 yuan per mu. 1. Cotton: Use insect-resistant hybrid cotton varieties such as Kemian No. 3 and Kemian No. 6. Before sowing, deeply plow the land 25 cm, and together with plowing, apply 3,000 kg of decomposed livestock and poultry manure and 60 kg of potassium sulfate compound fertilizer per mu. Broadcast 2-3 kg of 5% phoxim granules per mu to control underground pests. The suitable sowing period for cotton in Pizhou City is around April 3. Seize sunny days to raise seedlings in double-film nutritional pots. Prepare about 3,000 pots per mu of field. After watering the seedbed thoroughly, sow dry seeds, 1 seed per pot. About 0.35 kg of coated cotton seed is needed per mu of field. After full emergence, ventilate promptly to reduce humidity and control pests and diseases, and cultivate strong seedlings. Transplant around May 12 when cotton seedlings are at the 4-leaf stage, using equal-row spacing with a row spacing of 1.2 m and a plant spacing of 33 cm, planting about 1,700 plants per mu. In mid-to-late May, together with hilling, apply 15-20 kg of urea, 50 kg of superphosphate, and 20 kg of potassium chloride per mu. Around July 20, apply flower and boll fertilizer according to cotton growth, with 30 kg of urea and 15 kg of potassium chloride per mu. In early August, apply topdressing for boll development, with 7.5-10 kg of urea per mu. Pay attention to spraying trace element solutions such as boron fertilizer and monopotassium phosphate. Use mepiquat chloride for chemical regulation 4 times: 1-1.5 g per mu at the full bud stage, 2-2.5 g per mu at the early flowering stage, 3-4 g per mu at the full flowering stage, and 3-5 g per mu after topping. Top around August 6. Pay attention to controlling the third generation of cotton bollworm, cotton aphid, mirids, red spider mites, tobacco whitefly, and other pests. Pull up cotton stalks in mid-November.

What key points should be noted for late-planted rice when transplanting into fields prepared with stored water?
The general requirement for transplanting late-planted rice into fields prepared with stored water is to seize the water, prepare the field, and transplant the seedlings, increasing the number of hills, seedlings, and panicles. For rice fields transplanted with stored water, as soon as rainfall occurs or another water source becomes available, measures such as blocking, diverting, and pumping water should be taken immediately to seize the water, prepare the field, and transplant the seedlings. For late-planted fields, planting density should be increased. For seedlings aged 60-70 days, transplant more than 13,000 hills per mu (8 x 6 cun), with two seedlings per hill (2 grains of rice); for seedlings aged over 70 days, transplant more than 15,000 hills per mu (8 x 5 cun), with about 10 seedlings per hill, so that the number of seedlings planted per mu reaches 150,000
