Spreading early rice to prevent lodging

Scientific fertilization is the right amount of early nitrogen fertilizer. The early rice transplanting occurs early, and the manure should be chased after 3~5 days after the transplanting. The amount of the acre is about 7.5 kg of urea. The second is to increase the application of potassium fertilizer. In the period when the young panicles are differentiated to heading, the rice is most absorbed, especially the demand for potassium fertilizer is large. During this period, 8 kg of potassium chloride is used per mu.

Timely drying in the field, controlling seedlings and transplanting early rice, there are blasting characteristics of early and rapid tillering, and timely work on drainage and drying fields, so that the time is not equal to the seedlings (about 20 days after throwing), when the seedlings are not equal (mu The total number of seedlings reached about 350,000.) The sun was found to be cracked in the field, and the feet were not subsided. The combination of potassium fertilizer and uniconazole in the field was used to inhibit the internode length and increase the internode thickness.

Add uniconazole to 30 ml of 5% uniconazole emulsifiable concentrate per acre, add 0.5 kg of water to prepare a mother liquor, and then mix 5-10 kg of dry fine loess ash. After mixing well, spread the whole field evenly. Under normal conditions, the application of uniconazole generally does not occur.

In the middle and late period of the middle and late stage of irrigation, the water management should be based on the drying of the field, and the shallow panicle irrigation should be carried out during the differentiation of the young panicles to the heading and flowering stage, and the water should be rehydrated after the natural drying. During the filling and filling period, the method of dry-drying wet-wet gap irrigation is adopted. The shallow water is poured for 3-7 days, and it is naturally dried until the field is hard but there is no obvious crack and then re-watering.
