The heavy rainfall since August has caused millions of acres of farmland in our province to become flooded. On the 24th, the Provincial Department of Agriculture issued an emergency notice requesting relevant departments at all levels to promptly organize relevant experts and technicians to divide worksheets, strengthen technical training and services for farmers, and effectively strengthen autumn crop management in the field. The main management points of the main crops.
It is reported that currently the province's rain gills have expanded from west to east, while the autumn crops, especially corn, cotton, and peanuts, are in a critical period of production. The situation is extremely grim. Among them, the main points of post-maize management are: applying fertilizer to prevent premature aging. Flowering fill-up grain recovery, per acre can topdressing about 10 kg of urea. In particular, there are more rainfall in Lubei and other places. In addition to timely drainage, pay attention to nitrogen fertilizer application. After lodging, corn should be straightened and soil cultivated to restore the natural distribution of leaves and reduce yield loss. Strengthen comprehensive prevention and control of pests and diseases. In particular, it is necessary to strengthen the prevention and control of locusts and other late-stage pests, and spray pesticides to control locust spraying Tianda 2116, potassium dihydrogen phosphate and other foliar fertilizers. Appropriate late receipt, especially if the sowing date is postponed this year, it is even more necessary to insist on proper late-night income. The best harvest period should be around National Day.
The main points of peanuts' late management are: flood prevention, peanuts fruit ripening, water consumption plummeting, root water absorption capacity weakened, too much rain will cause root rot, stem failure, fruit rate reduction, and even rotten fruit disease, so pay attention Remove water and eliminate waterlogging. Prevent disease and prevent premature aging, combined with foliar spray fertilizer to prevent leaf spot disease. In general, per acre with 1% urea and 0.3% potassium dihydrogen phosphate mixed solution of 50-60 kg and 70% thiophanate-methyl wettable powder mix 800 times spray.
The key point of late cotton management is that the cotton fields should be rid of waterlogging, ventilation should be wet, drainage should be followed by ridge support, and soil should be lightly stepped on. After heavy rain, the loss of fertilizer in the cotton fields is serious, and foliar fertilizer such as urea and potassium dihydrogen phosphate should be sprayed to improve the nutritional status of the cotton plants and increase the boll weight. Pay attention to control of cotton bollworm, bridge-building insects, aphids, and red-leaf stem blight, verticillium wilt. The luxuriant cotton field cuts the middle and lower old leaves of the main stem and ineffective branches, improving the ventilation and light transmission conditions.
