The nursery seedling field is suitable to choose a leeward, sunny, fertile paddy field, the whole field when applying sufficient basal fertilizer to farmyard manure or green manure, 1600-2000 kilograms per acre is appropriate, with the water ploughing and harrowing, the field is flat and muddy, generally early July under the seedling, the planting density of 6 × 6 cm, the depth of planting requirements of the top buds of the third section of the bit of the soil into the soil of 2 centimetres, the depth of the water to keep about 3 centimetres.

The planting period of the mushroom seedlings can be based on the harvest time of the previous crop of rice, generally in late July to the end of August planting good. Before planting to prepare the field, when planting set up seedlings, remove the peripheral leaves, leaving only the petiole 16-20 cm long, so as not to be planted after the wind shaking, affecting the survival. Planting depth of about 10 centimeters, followed by the root soil can be filled, planting density 30 × (40-45) cm, mu planted 3900-4200 plants.

Field management

1, pipe water Izumi mushrooms throughout the reproductive period to maintain shallow water, to prevent drought, transplanted to shallow water and irrigation to improve the soil temperature, transplanted about a month, can be drained and set aside so that the roots are y rooted, a large number of beneficial plants to produce stolons, later to maintain a shallow water, to maintain the bulb expansion of the needs.

2, fertilization Izumi mushroom growth period is long, large fertilizer requirements, mainly base fertilizer, in order to continuously meet the Izumi mushroom growth and development of fertilizer requirements generally four times the appropriate fertilizer, base fertilizer per acre of 1500-2000 kg of farmyard manure, 50 kg of calcium; transplanting 10-15 days of the first application of fertilizer, mu ammonium carbonate 60 kg, 50 kg of calcium; transplanting 10-15 days of the first fertilizer, mu ammonium carbonate, 50 kg of calcium; transplanting 10-15 days of the first fertilizer, mu ammonium carbonate, 50 kg of calcium. The first fertilizer is applied 10-15 days after transplanting, 60 kg of ammonium carbonate, 50 kg of universal calcium; the second fertilizer is applied 30 days after transplanting, 60 kg of urea and 50 kg of potassium sulphate per mu; the third fertilizer is applied 45-50 days after transplanting, 20 kg of urea per mu.

3, plowing, weeding, leaf stripping This work can be carried out 30 days after transplanting, combined with fertilizer, and later should reduce the number of field operations, so as to avoid damage to the stolons of the Tzotzil mushrooms to affect the growth.

Disease and insect control

Autumn Izumi mushroom has relatively few diseases and insects due to the gradual decrease of temperature, the main diseases are Izumi mushroom spot disease, Izumi mushroom (solid ball black powder fungus) powdery mildew, and insect pests are mainly lotus constrictor aphid.

Prevention methods: ① after harvesting, thoroughly remove the disease and insect residues; ② choose disease-free sprouts; ③ reasonably dense planting, mu planting 4,000 appropriate; ④ strengthen field management, pay attention to ventilation and light and water slurry management; ⑤ apply fully rotted organic fertilizer; ⑥ pharmaceutical prevention and control of choice of the following agents: 15% powder rust 1500 times liquid; 70% methyl tolbutazin 1,000 times liquid; 36% methyl thiophanate 500-600 times suspension agent. Suspension 500-600 times solution; 90% Wanling powder 2300 times solution; 50% antiphlogistic 2500-3000 times solution. [1]?

Harvesting

The harvesting period of the fall Tzatziki mushrooms is on the long side, and it can be harvested and marketed in late November to February of the following year, and the above ground part is harvested just when it is yellowed, and it is not as productive as the delayed harvesting, which is due to the fact that after the stalks and leaves have withered and yellowed, nutrients in the shortened stems can still be transported to the bulb below the ground, so that the bulb continues to expand and increase the yield.
