Dryland millet "two methods" planting technology

Dryland millet two-planting technology
1. Basic Principles of Technology The two-planting technology of dry millet is a comprehensive cultivation technology for millet. Through horizontal trenches and furrows (two methods), intercepted rainwater, reduced surface runoff, and played a role in maintaining water and soil; deeper ditching is conducive to promoting Seedling and root development; it is favorable for invoking deep soil moisture and enhancing drought resistance; It is beneficial to concentrate deep-fertilizer and improve the utilization rate of fertilizer; it is conducive to reasonable close planting, making full use of light energy and soil strength; interchange of furrows and ridges can promote deep roots and leaves.
2 steps
2.1 The choice of plots of land less than 25 degrees slope, terraces, depressions, land can be planted, requiring more than 10cm plough layer, high fertility, containing 25ppm of available nitrogen, available phosphorus more than 5ppm. It is advisable to use artichoke or soy beans for the preceding crop.
2.2 After the land-planting autumn harvest, deep-dip more than 10cm, smash the soil, and mate for the winter. If the land is not hard to turn over in autumn, it will be planted in the early spring and the spring will be turned over (10cm or more). , with sowing seeds.
2.3 Fertilization Technology
2.3.1 Basic Fertilizer: Combine 8000-10000 kg of high-quality ring fertilizer and 300-400 kg of ammonium bicarbonate per hectare with the combination of fall-turning, and use 4000 kg of high-quality decomposed fertilizer, and apply superphosphate or 75 kg of diammonium phosphate as seed fertilizer. In the fall, the field without applying the base fertilizer can be used in the spring sowing of the base fertilizer and the seed fertilizer.
2.3.2 Top dressing: Before and after jointing, it will recover 100 kg/ha of urea.
2.4 Ditching sowing: Sloping land should be ditched along the contour lines from the top to the bottom, and one tilling or two tillers can be used. The row slope is 50cm, the terrace is 40cm, and the depth of the trench is about 13cm, so that the ditch, slippery seed, cover manure and kicking cover soil (3-4cm) can be completed once. Immediately after sowing, repression should be carried out. When coma (Astragalus membranaceus) is used, heavy repression should be carried out immediately.
2.5 Refurbishment of furrows and ridges: Artificial refurbishment of furrows and ridges after sowing is completed, so that the ridges are not incomplete, the furrows are smooth, and the land surface is free from rubble.
2.6 Drifting and arranging ridges: When the millet spreads leaves, combine the fertilization with the cultivator to cultivate the soil and break the ridge into the ditch so that the millet grows in the ditch and grows on the ridge.
3, supporting technology
3.1 Selection of improved varieties: Qingu No. 4, Qingu No. 5, and No. 1 seedlings were selected as the basis.
3.2 Suitable sowing, reasonable and close planting: The sowing time is appropriate from small to full-grown species, first to north and south, and gradually. About 9-10 strains of seedlings were planted on one-meter-long slopes, and about 180,000 strains were planted per hectare; 9 strains were planted on one-meter-long terraces, and about 220,000 plants were kept per hectare.
3.3 Strengthen field management and integrated pest management.
3.4 Timely harvesting: The grain at the base of the millet can be opened and harvested.
4. Economic and technical indicators: a yield of 3,000 kg/ha, an increase in yield of 30%, and an efficiency of 800-900 yuan/ha; the utilization rate of fertilizer will increase by 10%, and the water and soil loss will decrease by 50-80%.
5. Appropriate geographical conditions: Loess hilly and gully region (yellow soil, aeolian soil).
6. Explanation: The data comes from demonstration and promotion in Yulin area.
