1. When raising seedlings, you should choose leeward, sunny, fertile rice fields. When preparing the fields, apply enough base fertilizer. The base fertilizer is mainly farmyard manure or green manure. It is appropriate to apply 1600-2000 kilograms per mu, with water. Plow, level and muddy the fields, and usually plant the seedlings in early July. The planting density should be 6 × 6 cm. The planting depth requires the third node of the top bud to be 2 cm deep, and the water depth should be maintained at about 3 cm.

2. The planting period of the mushroom seedlings can be determined according to the harvest time of the previous rice crop. It is generally planted from late July to the end of August. Before planting, you must prepare the seedlings. When planting, lift the seedlings and remove the outer leaves, leaving only 16-20 cm of petioles to avoid shaking in the wind after planting and affecting survival. The planting depth is about 10 cm and then the roots are filled with mud. The planting density is 30×(40-45) cm, and 3900-4200 plants per mu are planted.

3. Field management

(1) During the entire growth period of the tuber mushroom, shallow water should be maintained to prevent drought. After transplanting, shallow water should be irrigated frequently to increase the temperature. After transplanting, it should last for about one month The water can be drained and placed in the field for a month to make the roots take root deeply, which is beneficial for the plants to produce a large number of stolons. In the later period, the water should be kept shallow to maintain the need for bulb enlargement.

(2) Precise fertilization plan: Fertilization: The mushroom has a long growth period, so it requires a large amount of fertilizer and is mainly based on base fertilizer. In order to continuously meet the requirements for fertilizer and water for the growth and development of the mushroom, it is generally appropriate to fertilize four times, with the base fertilizer Apply 400-500 kilograms of bio-organic fertilizer per mu; apply the first fertilizer 10-15 days after transplanting, and apply 50 kilograms of potassium sulfate compound fertilizer per mu; apply the second fertilizer 30 days after transplanting, apply 50 kilograms of potassium sulfate per mu kg; apply the third fertilizer 45-50 days after transplanting, and apply 50 kg of potassium sulfate compound fertilizer per mu.

(3) Plowing, weeding, and leaf stripping. This work can be carried out in conjunction with fertilization 30 days after transplanting. In the future, the number of field operations should be reduced to avoid damaging the stolons of the mushroom and affecting its growth.

4. Prevention and control of diseases and insect pests

As the temperature gradually decreases in autumn, there are relatively few diseases and pests in the mushrooms. The main diseases include mushroom spot and Ustilago mushrooms. Ustilago, the main insect pests include lotus aphids.

Prevention and control methods: Thoroughly remove pest and disease residues after harvest; select disease-free seedlings; plant reasonably densely, with 4,000 plants per mu being suitable; strengthen field management, pay attention to ventilation, light transmission, and water slurry management; Apply fully decomposed organic fertilizer; for chemical control, choose the following chemicals: 1500 times the solution of 15 thiophanate; 1000 times the solution of 70 thiophanate methyl; 500-600 times the solution of 36 thiophanate methyl; 2300 times the solution of 900,000ml powder; 50 pirimicarb 2500-3000 times solution.

5. Harvesting

The harvesting period of autumn mushrooms is longer. They can be harvested and put on the market from late November to February of the following year. They are harvested when the above-ground parts have just withered and turned yellow. The yield is not as high as that of delayed harvesting. This is because the nutrients in the shortened stems after the stems and leaves wither and turn yellow can still be transported to the underground bulbs, causing the bulbs to continue to expand and increase yields.
