1, early seedlings, early seedlings, reasonable close planting. "In the valley, like dung." The early summer seedlings in the dry land can promote strong seedlings; seedlings and seedlings in the evening are contending for water, and individuals are stunted, which can easily cause seedlings shortage. Generally can be in the seedlings 4 leaves a heart time, Dingmiao, fight for all in the 7 leaves before the end. When the seedlings should be used to leave the triangle method, seedling distance 3 - 4cm, between the weak seedlings, variegated seedlings, seedlings, 667m2 Liumiao 4 - 50,000 strains. 2, Sancha, Sanhe, strong root promoter. After sowing, "Sanhe" and "Sanhe" are the important measures for strengthening seedlings, strengthening roots, promoting culm, and promoting the panicle in Xiagu dryland. The Sancha is: After sowing, it is followed by sowing and pressing once to make the seeds in close contact with the soil so as to make it absorb water and germinate. The yellow buds are budded and the second repression occurs when the budding sheath is unearthed after three days sowing; The third crackdown took place as soon as it reached a leaf. Rolling pressure should be carried out in the sunny afternoon, and dryness is not damp. Through rolling, the valley seedlings can be promoted to be strong and healthy. Sanchao is: the combination of shallow seedlings to remove weeds, stabilize the seedlings around the soil, and promote seedling roots undershoot; jointing period, the root growth into the first peak, in order to promote root development, to carry out a deep cultivator to break The soil is compacted and can be rammed by soil; the root development at the booting stage enters the second peak period, at this time it is necessary to squat 10 cm to cut off the old roots and promote new roots. Due to the high temperature and rainy season during the summer season, it is not conducive to the production of millet. By deep boring, we can improve the condition of soil ventilation and create a condition conducive to rooting and cultivating roots in Xiagu. This will lay the foundation for the formation of later production. 3, scientific application of fertilizer, re-application of booting fertilizer. According to the test, the price of 667m2 in summer produces 100kg of grain, which needs to absorb 2.5kg of pure nitrogen, 1.2kg of phosphorus and 2.4kg of potassium from the soil. Therefore, only the application of basic fertilizer and skillful application of fertilizer can meet the needs of growth and development in summer valley. The seedling stage of the millet requires less nitrogen fertilizer. When sowing, 667m2 of urea can be applied to 3kg. The amount of fertilizer required at the jointing stage is increased, and 7 kg of standard nitrogen fertilizer can be applied per 667m2.
