How to grow millet? How to grow millet?

1, selective land rotation

Because the millet seeds are small, the buds are weak, and the top soil ability is poor, so the millet should be planted on the plots with loose soil, flat terrain, thick soil layer, good drainage and irrigation and high organic matter content. After the land is selected, it should be carefully prepared to make it a whole. Millet should be rotated to eliminate stubble, avoiding repeated stubble (continuous planting of millet in the same field) and not following stubble (planting millet in the same field every other stubble). Millet rotation usually takes 3-4 years. The first crop of millet is preferably beans and green manure, followed by wheat and corn.

2, fine soil preparation, sufficient base fertilizer.

Fine soil preparation can prevent drought, preserve moisture and protect seedlings. Soil preparation should start early. When the soil is frozen deep, it should be ploughed in time, combined with shallow ploughing, and sufficient base fertilizer should be applied. Generally, 5000 kg of farm manure and 0/5 kg of diammonium phosphate are applied per mu, and raked immediately after ploughing. After soil preparation, the soil should be fine, thorough, flat and velvet, the upper part should be empty and the lower part should be solid, and there should be no residual plants and stubble.

Step 3: sow.

(1) Sow millet seeds in time. The lowest temperature of germination is 7-8℃, and the optimum temperature is about 65438 03℃. Seedlings are not tolerant to low temperature, so the sowing date of millet should be adapted to local conditions. Zhangye area is suitable for sowing from late April to early May. Seed dressing with 50% carbendazim according to 5% of seed weight can control head smut.

(2) Sowing amount and sowing depth Calculate the sowing amount according to the required number of seedlings, germination rate, true impurity rate and 1000-grain weight. Generally, the sowing amount per mu is 1- 1.5 kg. The sowing depth is based on the principle that the soil moisture is shallow and the soil moisture is poor, and the sowing depth is 3-4 cm.

(3) Sowing methods There are many sowing methods for millet, among which threshing and mechanical sowing (drill sowing and hole sowing) are common.

(4) The sowing requires the use of rotary sowing or seeder, and the sowing is required to be even, without missing sowing, continuously ridging, with the same depth, and timely suppression after sowing. Plots with severe spring drought and poor soil moisture can increase the number of repression and improve the emergence rate.

4. Tian Tuan management

(1) seedling management should do well in seedling protection, squatting, thinning and weeding. Interplanting at 3-leaf stage and fixing seedlings at 5-leaf stage, with row spacing of 18-20 cm and row spacing of 8-18-00 cm; The hole spacing is 20cm, the row spacing is 20cm, 2-3 plants are left in each hole, and 37,000-42,000 plants are protected per mu. Combined with thinning or fixing seedlings, shallow intertillage is used to cultivate millet seedlings, which promotes strong seedlings, weeding and moisture conservation. When fixing seedlings, leave seedlings with consistent growth, green seedlings without yellow seedlings and strong seedlings without pests and diseases. False hybrids should be pulled out when seedlings are fixed between hybrids.

(2) From jointing stage to heading stage in late June, the jointing stage is combined with watering, deep ploughing and intertillage, and topdressing urea 15 kg/mu. Combined with watering at booting stage, topdressing 20-25 kilograms of ternary compound fertilizer per mu, timely intertillage for weeding, and intertillage more during drought, which can not only increase production, but also improve rice quality.

(3) Special herbicide spray for millet can be used to remove common annual monocotyledonous weeds and dicotyledonous weeds, such as crabgrass, barnyard grass, green bristlegrass, cattail and Chenopodium. , save labor and effort. It can be sprayed on the soil surface after sowing and before emergence, or before weeds are unearthed in the 3-5 leaf stage of rice seedlings, and it is not suitable for use when seeds are covered with soil.

Step 5 control pests and diseases

(1) Millet is vulnerable to corn borer and underground pests at seedling stage and jointing and heading stage. If there are pests, it can be controlled by spraying 50 ml of 5% phoxim and 40 kg of water per mu.

(2) Pay attention to prevent bird damage and lodging of millet from filling to maturity, especially early-maturing varieties.
