Planting method and time of Coix barley

Barley rice is generally planted by water or dry planting, and the best time is mid-June. When sowing, we should choose the fertile vegetable garden as the seedling bed, and then use the water planting method of planting 2-3 seedlings per clump or the dry planting method of 2-3 seedlings per hole.

Planting techniques of Coix barley

1. Land selection and preparation

Barley can be planted in all kinds of soils suitable for the cultivation of flue-cured tobacco, and the riverside sandy loam with better irrigation conditions is often used to grow barley. According to different planting methods, soil preparation methods can be divided into two types: (1) water cultivation method. Same as paddy field preparation, first irrigate and dissolve the field, then use mechanical ploughing or livestock ploughing to rake and straighten it, and then plant it; (2) dry planting method: ploughing and ploughing with artificial, mechanical or animal power, raising ridges and planting borders, the width of the border is generally 70~80cm and the width of the ditch is 20~30cm.

two。 Water and fertilizer

It is based on the principle of "wet-dry-water-wet-dry" management, that is, wet seedling raising, dry jointing, water booting, sufficient water heading, wet grouting and dry field harvest. The method and quantity of fertilization are determined by the fertilizer requirement characteristics of Coix barley and the fertilization level and habits of different places. Attention should be paid to the reasonable proportion of base fertilizer and topdressing fertilizer. Chemical fertilizer can be used for topdressing of barley rice, which can be applied at young panicle and heading stage.

3. Pollination

Coix barley is a hermaphroditic plant. In the same inflorescence, the male flower matures first and is not synchronized with the female flower. It often requires heterologous pollen fertilization. Generally, pollination can be completed by wind pollination. At 10: 12 in the morning at the peak of flowering, ropes and other tools are used to vibrate the plant to make the pollen fly, which has an obvious effect on improving the seed setting rate.

4. Pest control

The common diseases of barley include smut (also known as smut) and leaf blight, and pests such as corn borer and aphids. Growers should take control measures on the barley fields in advance and spray pesticides on the diseased plants in time.

Due to the inconsistent ripening of barley seeds, 80% of the seeds are discolored and hardened and full. After harvest, several kinds of barley should be dried for 3-4 days, and then threshed.
