First, moderately put aside fields. The paddy field should generally be carried out at a time when the rice is not sensitive to the water reaction, that is, it is suitable from the late stage of tillering to the early stage of young panicle differentiation. Operation should follow the following principles, namely, Miaowang Miaowang proper early settling; Mud feet deep, there are leggy phenomenon to roast more, otherwise it is lighter; Bad water retention fields, should not be re-rested;
Second, scientific irrigation The long panicle stage is the peak of physiological water demand in rice in a lifetime, especially in the 2-14 days before heading, it is most sensitive to water reactions, and water scarcity is necessary so as not to affect the differentiation and development of spikelets. After reclaiming the field, rehydration should be done in shallow water and groundwater irrigation should be conducted with the method of “Chen water is not dry and new water is not availableâ€. Scientific irrigation after field baking has not only saved valuable water resources, but also improved the ecological environment of the soil, maintained and improved the vitality of the roots, and facilitated the absorption and running of nutrients.
The methods of irrigation during heading and fruiting period are: heading in deep water, grouting in shallow water, moist seeding, draining and draining about 5 days before harvest. Avoid cutting off water prematurely and affecting grain weight.
Third, the clever application of panicle ear fertilizer is generally applied after the initiation of young panicle differentiation, the amount should be based on the growth of the rice field may be: too many stem pods, leaf color to be less concentrated, late application, mu urea 2.5-3 Kilograms can be; lack of stem pods, yellow leaves and different shades of early application, re-application, mu urea about 5 kg.
Increasing grain fertilizer is mainly a deficiency of supplementary fertilizer. The best application period of granular fertilizer is the period when the rice leaves can be naturally reduced before the break, that is, it is suitable for topdressing after 2-3 days before heading. Urea is generally preferred for granules, and 2.5 kg for mu. However, it is not suitable to apply granule fertilizer in order to prevent late-maturing gluten and affect yield and quality. To prevent premature plant growth after heading, leaves should be sprayed at this time, you can use rice special leaf fertilizer "increase 100 pounds" in the sunny afternoon afternoon spray, spray should be sprayed on both sides of the blade.
Fourth, pest control Rice paddy in the middle and late stages should focus on the prevention and control of bacterial blight, sheath blight, rice false worms and borer borer, rice borer borer, rice planthopper and other pests and diseases, and these diseases and insect pests multiple compound occurrence. According to this actual situation, pesticide compounding technology should be used for compound prevention and control, such as bacterial leaf blight, Sanhuaxi and other compound hazards, the control of the mixture of Ye Kuning and insecticidal double can be used to prevent and treat this problem. It also played a good control effect.
