First, water management: Rice grouting nutrients rely mainly on the top three green leaves photosynthesis to provide nutrients to supply, in order to maintain these three green leaves do not premature aging, we must maintain the vitality of the roots, and increase the permeability of the soil in order to maintain the root system Vitality, therefore, this stage should take intermittent wet and dry intermittent irrigation measures to increase the oxygen in the soil, maintain root vitality, and ensure the light and ability of the three leaves. Individual hypertrophy overgrown the black plots to drain the water to dry the fields, lighten the leaves and rehydrate. The withdrawal of rice is generally appropriate around September 15th. With proper water withdrawal, the root activity can be maintained, the leaves are not prematurely decayed and the grain plumpness is increased. Low-lying meadows can be withdrawn as early as possible.
Second, topdressing granular fertilizer: rice filling requirements of light green leaves, if the pale yellow leaves of fertilizer, you should follow the application of fertilizer, 5 to 7 kg of ammonium per acre to recover urea or ammonium sulfate, can increase the speed of grouting , Increase the weight, top dressing time is completed within 10 days after emergence.
Third, prevention and control of pests and diseases: (1) Prevention of stem and shoot pods is a key link in affecting rice yield. At present, there are many types of rice varieties that are difficult to discern and are difficult to discern. The types of rice cultivars that are truly resistant to rice blast are few, combined with the current heavy rain, haze and fog, In order to facilitate the occurrence of panicle shoots, the majority of rice farmers must attach great importance to it. In order to ensure the final harvest, we must comprehensively prevent and treat it, and apply it twice during the break period and at the heading stage. At present, the better agents are: take the enemy stable (trichothecene hexaconazole), Indazole (Fuji No. 1, Feng F, Sarawan, etc.), DHS (tribenoxime, hexanoxazole, difenoconazole) , rice straw amide, tricyclazole, kasugamycin, etc., the amount of liquid spray per mu can not be less than 60 pounds. (2) Rhizoctonia solani is also an important disease that affects the maturation of rice groats. It has occurred in recent years, showing decay of leaf sheaths and yellowing of the bottom leaves. The occurrence of excessive nitrogenous fertilizers and excessively prosperous land masses can be combined with rice blast prevention at the time of breakage. The main agents include Jinggangmycin and Fusarium sibiricum. (3) The second-generation armyworm has been in existence for two consecutive years. This year, it is still necessary to pay close attention to it.
Fourth, to promote early maturing: At present, rice has been harvested, in order to obtain a better harvest, can be combined with anti-spike stem pods at the same time to promote the application of mature foliar fertilizer, can increase grain weight to promote maturity. Better foliar fertilizers are: Baofengling, grouting grain granules, Brassinolide (Babao, Azengmei).
