The planting method of Pleurotus ostreatus (scissors grass)

Sagittarius is a kind of vegetable, but also a medicinal material, set edible, medicinal and ornamental value as a whole, has a high economic value, today Xiaobian will introduce you to the cultivation method of Sagittarius.

1. Select improved varieties

Before and after the beginning of spring in March every year, mature corms with strong growth, good appearance, appropriate size and no abnormal diseases and insect pests should be selected as seeds, and then the selected seeds should be directly inserted into the prepared seedling bed for planting and cultivation, generally with the specification of 10*10cm, plastic film should be covered on the seedlings after insertion, and the water level of the seedling bed should be kept at 2- 4 cm, and germination will begin after almost half a month. After a month, seedlings will sprout.

2. Seedling temporary planting

Sagittarius pseudo-planting is generally after the seedlings grow out, that is, after the middle of April, when the surrounding temperature has stabilized at about 15 degrees, you can start pseudo-planting, pseudo-planting land should be selected in the leeward sunny, fertilizer and water sufficient, no previous disease in the paddy field, the distance between each plant should be maintained at about 0.5 meters, row spacing at about 0.7 meters, the paddy field around the establishment of a good ridge, to ensure that there is sufficient water in the field, so that seedlings continue to pull out stolons, When the stolon is underground, the terminal bud will develop into many ramets. Only when these ramets grow into standard seedlings can they be transplanted to the field. When planting, pay attention to weeding frequently, remove useless leaves, and apply farm manure at least twice.

3. Finishing the field

Field plantations should be selected in paddy fields with sufficient and clean water, convenient drainage and irrigation, and rich soil. Rotation should be carried out. Before planting, about 1000 kg of farm manure should be applied to each mu of the field as base fertilizer. The growing seedlings of arrowhead should be strong and at least 25cm high. The central leaves of seedlings should be kept. About three old roots and leaves that cannot grow and develop should be cut off. Generally, planting should be started from early August to early September. The distance between each plant is about 25cm, the row spacing is 60cm, the field is well drained and irrigated, the field surface is leveled, shallow water is inserted, and 50 more plants are inserted on the field surface as standby seedlings.

4. Field management

Pay attention to inspection at all times within three days after planting. If lodging seedlings are found, they should be righted, diseased seedlings with poor growth and serious diseases and insect pests should be pulled out in time, and then seedlings should be taken from spare seedlings to supplement seedlings. One month after planting, seedlings can be properly placed in the field for a short period of time, subject to the condition that their feet will not sink into the field. About half a month after planting, when the plants grow out of several true leaves, the field should be weeded by intertillage, and redundant weeds in the field should be removed. Sacculus seedling plucking, pay attention to more nitrogen fertilizer, appropriate combination of phosphorus and potassium fertilizer.

The above is a small series of finishing the cultivation method of arrowhead, I hope it can help you!
