After the rice is planted, strengthen the field tube

After transplanting rice, it is necessary to strengthen field management in time and promote early-onset rice growth. The following technical measures are mainly implemented: To strengthen the management of paddy rice seedlings in the field of water slurry management, and to adopt the method of irrigation with deep-water live trees and shallow-water pods after planting to ensure early seedlings Live tree, early delivery. The live field should timely irrigate the horse water after sowing to ensure early seedling emergence and early seedling development. At the same time, it is necessary to clean up and match the furrows in the fields so that it can be filled with water and energy, and a shallow water layer can be established in the 2 leaves and 1 heart period to promote early delivery.

Early application of sub-fertilizer after returning green plants in the rice, timely recovery of fertilizer application, usually 5 ~ 7.5 kg of urea per acre. After the first top dressing, 7 to 10 days, depending on the amount of birth in the field and the shade changes of the seedlings, appropriate balance fertilizer or strong fertilizer is applied, and 3-4 kg of urea per acre is used. For the lack of basic stems and seedlings, as well as machine-inserted, live-broadcast plots, appropriate additional application of tiller fertilizer.

In a timely manner, 5 to 7 days after the weeds are transplanted, weed herbicides such as butylate are used to control weeds in the field, and the shallow water layer is kept for 5 to 7 days after the application.

Strengthen pest control Every year, the occurrence of Laodelphax striatellus is large and the rate of poisoning is high. Rice stripe blight has a tendency of pandemic, and planting areas of susceptible varieties such as Wuyujing No. 3 and Wuyunjing No. 8 have increased. Therefore, in addition to transplanting with drugs, the first medication should be administered immediately 3 to 5 days after the rice is planted, and the medication should be repeated every 4 to 7 days. Indica rice was used 3 to 4 times, and hybrid rice was used twice.

To promote the transformation of seedlings, improper management of fertilizers, or abnormal weather and other unfavorable factors resulting in the failure of fresh seedlings, spraying appropriate growth regulators in time to promote seedling transformation.
