The importance of transplanting rice seedlings is not only simple to complete the transplanting work, but also more important is how to improve the survival rate of rice blast, the rate of hair growth and the benefit of increasing production. Therefore, in addition to transplanting rice bran, we must also do the following:
First, the rice fields must be intensively cultivated. First of all, we must make full use of sunny weather to turn over the soil and land, and do a good job in advance to plant flat land in Hiroshima. Each piece of paddy field is required to be cultivated and flat, the horizontal line is the same, and the soil is required to be deep, loose, and soft. In general, paddy fields must be ploughed first, then rotated and then leveled. The weeds from the upper stalks should be turned into the soil and the weeds and unbalanced mud piles on the fields should be found. The rice stalks should be transplanted. Provides good leveling conditions.
Second, timely shallow water transplanting. According to the timely transplanting of rice cultivars and seedlings in shallow water, the average age of transplanting rice seedlings should be controlled at about 30 days, and the seedling age at plastic trays in dry land should be about 25 days. Generally about 24,000 mu of seedlings are planted in the early rice field, and about 22,000 mu are planted in the middle and late rice. When transplanting, it is necessary to plant shrubs in shallow water. The water depth should be 2-3 cm. It is advisable to throw 1-2 cm of shallow water in the flood field. The seed oil field in direct seeding rice should be thrown by waterless wet land, regardless of the transplanting method. Should not be transplanted in deep water.
Third, apply enough organic fertilizer. According to the "four types of one" formula fertilization requirements, in the farming when the Pingtian enough organic fertilizer, usually farm-based fertilizer, such as cake fertilizer, or market sales of organic fertilizer 40-50kg, superphosphate or diammonium phosphate 10- 20kg, at the same time, it can apply 2kg of aerodynamics per acre of rice field. The polar motilin has a function of dissolving and releasing potassium, strong power, long-lasting fertilizer effect, improved soil structure, and improved efficiency of fertilizer utilization. It also eliminates the need to use chemical fertilizer to fight ostomy. The transplanted seedlings simply do not have the ability to attract fertilizers, and they can't stand the soaking of high-concentration nitrogen fertilizers. Otherwise, they can easily cause the phenomenon that the seedlings are not growing.
Fourth, scientific fertilizer management. According to the technical requirements of the “four types of one†formula, the top dressing should be topped with 5-10 kg of urea and potash after the 4-5 days of planting, ie when the seedlings begin to take root, and be mixed with herbicides to spread fertilizer. The effect of cultivating and weeding. After 2-3 weeks, 10kg of urea fertilizer, 15kg of potash fertilizer or 15kg of compound fertilizer is applied to the hair tree, which is advantageous to the rapid development of rice crops and the role of multiple heading and harvesting. It can produce 5-10 rice panicles more than traditional rice fertilization methods. The principle of high-increased production of four-in-one formula fertilization is among them. During the period from booting to heading, it is possible to mix and spray Kouxiaowangye and K.sterilizer, once a week, not only can effectively prevent rice sheath blight, Aspergillus and other diseases, but also can effectively prevent lodging of rice stalks and promote grain filling. Precocious function, other pests and diseases can be controlled by conventional management methods.
