In order to reduce the losses caused by floods as much as possible, some fresh autumn peanuts can be developed on the plots along the Yangtze and Jiangnan areas due to floods. The technical points are as follows:
1. Use early maturing varieties. Early-maturing varieties Luhua No.9, No.13, No.14, and Huanhua No.2 were selected.
2, grab the time to broadcast early. Seeding should be completed by July 20.
3. Increase density. 13,000 holes per acre, double holes per hole.
4, covered with plastic film. In order to increase the effective accumulated temperature and protection, and ease the contradiction of the season, it is advisable to adopt the method of mulching and mulching. Pay attention to the timely opening of the seedlings, that is, when the apical membrane of the peanut topping soil (just seeing the green leaves), the membrane is unearthed in time to open the membrane, and then a piece of soil is placed on the membrane hole. When two true leaves are displayed, Immediately blight the soil and release the first pair of side branches. Other measures are carried out as usual.
5. Fertilization management. Conditional acreage of 10 kg of urea, 45 kg of superphosphate, 10 kg of potassium sulfate, mix well, before planting combined with land preparation, spraying 1% to 2% of urea solution 50 kg in the middle and late period, to prevent premature aging, increase yield .
