Post-disaster crop management
Affected by the heavy rain, all the big autumn crops have been affected by floods and floods of varying degrees. Some crops have been drowned and harvested. To minimize the damage caused by the disaster, the majority of farmersâ€™ friends are required to act quickly to take the following measures and strengthen Field management.
First, the assault cleans up the ditch, grabs time to drain. Promptly transport the field ditch to deepen the low slops and the corresponding drainage ditch, drainage and drop as soon as possible to reduce wetness.
Second, pay close attention to washing seedlings, planting. As soon as the field can establish its footing, it is necessary to quickly help the seedlings and wash the seedlings to wash the paste on the leaves and stems to restore the photosynthesis of the leaves. The younger the volunteers should fight for the better. We must lightly avoid breaking branches and leaves and prevent new wounds in the root system.
Third, timely transfer, spray foliar fertilizer. After lack of rainstorm, the phenomenon of water seedlings is very serious. It is necessary to quickly grab the tune and spray foliar fertilizer. About 1 g of spring cotton acre is used in the treatment of contractile amines, and after the wheat is made of cotton, 0.5 g of the dipsticks are mixed with water. spray. The combination of tone must be sprayed Sonic boron plus potassium dihydrogen phosphate 2-3 times.
Fourth, scientific recovery fertilizer. After the weather is fine, we must seize the easy tillage period to quickly recover fertilizer, cotton to replant early flower bell fertilizer, Mushi cotton formula fertilizer 80 kg plus potash 30 kg, without applying basic fertilizer corn field Mushi corn formula fertilizer 80 kg, applied base fertilizer Urea urea 30 pounds of corn fields, formula fertilizer 40 pounds. Do a deep ditch, quickly promote the onslaught, as soon as possible to cotton into the increase, increase buds, flowering, the peak period of the bell, the corn grows weak, strong, increase the ear.
Fifth, strengthen the cotton plant pruning. When the flooded cotton plants recover, the axillary buds in the latent limbs below the fruit branch will rapidly develop into leaf shoots, and the latent shoots on the leaf sections above the fruit branches will also grow into larger axillary buds, which will consume the body of cotton plants. Numerous nutrients, in order to ensure adequate supply of nutrients for late bud bells, the pruning work must be strengthened and the leaves and axillary buds must be quickly removed.
Six, grab the sun, cultivator, loosen the knot. After the water discharged from the field, grab the cultivating soil in the easy tillage period and remove the field compaction, increase the soil permeability, improve the root environment, and promote root growth.
Seven, pay attention to pest control. After the heavy rain, the oranges of cotton will be wilt. The incidence of stalk rot and the size of leaf spot disease in corn will be more serious. Attention should be paid to the dehydration, filtration and spraying of pesticides. At present, the main pests in the field include blind stink bugs, cotton bollworms, aphids, red spiders, and corn borers, etc., and biological and chemical agents are alternately used for prevention and control.
VIII. For crops that have not been harvested, vegetables, green beans, corn and other crops should be quickly replanted. (Hubei Dangyang Agriculture 110 Zhu Liqing)
