Soybean ridge three cultivation to increase yield
Soil deep loose technology. The depth of deep soil is based on the bottom layer of the hitting and plowing plough. Generally, the depth of deep boring is appropriate to 25--30 cm. According to different parts of deep pine, it can be divided into deep ridges, deep ridges and all-round deep pines. There are two methods for deep loosening of ridges: One is deep soil preparation, also called deep ridge ridge. This method is used in combination with site preparation for deep ridges, such as deep mashing and deep slashing on the basis of ploughing or hoeing; the other is deep sowing. Using a large "three-ridge" tillage machine, deep fertilization and deep sowing of the ridge body are performed simultaneously with deep fertilization and precision seeding. This method is a one-time completion of three technologies. Deep ditch is used for deep loosening of ditch with deep spade shovel. According to the different growth period, it can be divided into sub-deep and deep ditch before seeding, deep ditch at seedling stage, etc. It can also be used for small-sized “ridge three†tiller. At the same time, the ditch is deep and loose. All-round deep looseness refers to the use of a full-range deep-soiler to loosen the entire plough layer, so that the soil layer can be undisturbed, and the cultivating layer can be deepened. The depth of deep soil can reach more than 50 cm. Fertilizer deep application technology. Fertilizer as a fertilizer, the depth of fertilization should be more than 10 cm, that is, fertilizer applied in the species of 5 cm is appropriate. Fertilizer base fertilizer, fertilization depth to reach 15-20 centimeters, that is applied in the species 10-15 centimeters is appropriate. At present, the small-scale precision seeder used in production can do deep fertilizer application; the large-scale “three-ridge†planter produced by Yilan and Helen in Heilongjiang Province can not only make deeper fertilization, but also can do fertilizer and base fertilizer at the same time. Application, that is, layered fertilization. Precision seeding technology. Sophisticated sowing is an important technical measure for realizing uniform distribution of soybean plants, overcoming shortage of seedlings and air-breaking, reasonably close planting, and increasing yield. At present, except in places where the labor force is sufficient, the farmers also use artificial precision seeding methods such as artificial gazing and artificial seeding, and most regions have used mechanical precision seeding. The mechanical precision seeding can do the ditching, seeding, fertilizing, earth covering, and suppressing continuous operations, which not only accelerates the sowing progress, shortens the sowing date, but also ensures the sowing quality. Soybean "Ridge III" cultivation technology is not only a simple combination of the three technologies, but also must cooperate with other cultivation techniques, such as selecting suitable and suitable varieties, and strictly selecting seeds; implementing Fuqiu's fine soil preparation; timely broadcasting, ensuring Sowing quality; Rational fertilization, increase organic fertilizer; Strengthen pest control, field management, etc., in order to maximize its potential to increase production.
