The planting method of Cigu

Sagittarius is also known as swallowtail grass, belonging to perennial herbs, in the north and south of our country have a large area of planting range, many friends sagittarius is water chestnut. But otherwise, because the appearance of water chestnut is black flat, the appearance of arrowhead is white oval, looks completely different, just because many local dialects, called water chestnut "arrowhead". Sagittarius has the effect of detoxification, diuresis, strengthening and moistening the body. Today, Xiaobian brought you the planting method of Sagittarius. Let's take a look at it together!

1. Select improved varieties

Before and after the beginning of spring in March every year, mature, strong growth, good appearance, suitable size, and relatively sturdy terminal buds without abnormal diseases and insect pests should be selected as seeds. Then, the selected seeds are directly inserted into the prepared seedling bed for planting and cultivation, generally in the specification of 10*10cm. After planting, plastic film is covered on the seedlings, and the water level of the seedling bed is kept at 2- 4 cm. After about half a month, the seedlings will begin to germinate, and after one month, the seedlings will grow.

2. Seedling temporary planting

Sagittarius pseudo-planting is generally after the seedlings grow out, that is, after mid-April, when the surrounding temperature has stabilized at about 15 degrees, you can start pseudo-planting, pseudo-planting should be selected in leeward sunny, abundant fertilizer, no previous disease in the paddy field. The distance between each plant should be kept at about 0.5 meters, and the row spacing should be about 0.7 meters. The paddy field should be surrounded by a good field. It should be ensured that there is sufficient water in the field, so that the seedlings can continuously pull out the stolons. When the stolons are underground, the terminal buds will develop into many ramets. Only when these ramets grow into standard seedlings can they be transplanted to the field. Pay attention to weeding frequently, remove useless leaves and apply farm manure at least twice.

3. Finishing the field

Field planting field should choose paddy field with sufficient clean water source, convenient drainage and fertile soil, rotation should be implemented, and about 1000 kg farm manure should be applied per mu as base fertilizer before planting. Sagittarius growth seedlings to be robust, at least 25cm high, retain the central leaves of seedlings, about three, will not grow and develop the old roots, old leaves cut off. Usually in early August to early September when planting, the distance between each plant is about 25cm, row spacing in 60cm. Irrigation and drainage facilities are prepared in the field, the field surface is leveled, shallow water is inserted, and 50 more plants are inserted in the field surface as standby seedlings.

4. Field management

Pay attention to patrol at all times within three days after planting. If lodging seedlings are found, they should be righted, and diseased seedlings with poor growth and serious diseases and insect pests should be pulled out in time, and then seedlings should be taken from standby seedlings to supplement seedlings. A month after planting, seedlings can be properly placed in the field for a short period of time, so that the feet will not sink into the field. About half a month after planting, when the plant grows out several true leaves, the field is cultivated and weeded, the redundant weeds and capsule seedlings in the field are pulled out, and attention is paid to applying more nitrogen fertilizer and combining phosphorus and potassium fertilizer appropriately.

The above is a brief introduction to the cultivation method of Sagittarius. The cultivation of Sagittarius is not difficult, but it also needs its own careful care. Without a correct planting technique and management method, it is impossible to achieve the goal of high yield and high yield. In the planting process, we also need to pay attention to the prevention and control of pests and diseases, pests and diseases to arrowhead damage can be devastating, if not dealt with in time, will greatly reduce production or even yield.
