How to manage high yield of peanut in late stage?
How to manage high yield in the later stage of peanut? Is there a good way to achieve it? Also ask experienced netizens to help introduce the peanut plants appear full to most pods mature harvest as its late growth stage. During this period, the vegetative growth of peanuts gradually declined and stopped, and the pods were gradually full and full, and the increased fruit weight generally accounted for 500%-70% of the total fruit weight, which was the main period of pod yield formation. Therefore, the farming network sorted out the four key points of management in the later stage of peanut growth, which are listed in detail below for netizens' reference. The main points are as follows: 1. Fertilizing outside the root to protect peanut leaves: the absorption of nitrogen, phosphorus and potassium in the late growth stage of peanut accounts for 6.3%, 5.3% and 0.75% of the total absorption during the whole growth period, respectively. Although peanuts need less nutrients during this period, it has a great impact on the formation of yield and the improvement of pod plumpness. The absorption capacity of peanut roots decreased in the later stage, and in order to make up for the lack of fertilizer supply, from the late pod-setting stage, 1%-2% urea and 2%-3% calcium superphosphate aqueous solution were sprayed 2-3 times every 7-10 days, 50 kg per mu each time, in order to prolong the functional period of the top leaf and improve the fullness rate of pods. Point 2, timely watering peanuts: in the late growth stage of peanuts, the appropriate soil moisture is 50%-60% of the maximum capacity in the field. In the event of drought in this period, the root system is easy to decline, and quickly cause top leaf shedding, stem and branch withering, reducing the rate of full fruit, leading to a reduction in yield. Therefore, when the soil moisture is less than 40%, it should be watered immediately to protect the roots and leaves, improve the satiety rate, and irrigate in small ditches or sprinklers when watering, and avoid flooding. Point 3, timely drainage in rainy days to prevent peanut rotten fruit: in the late growth stage of peanut, if there is too much autumn rain and poor drainage, it is easy to cause root rot, and in serious cases, pods will rot or sprout. Therefore, when there are too many Rain Water in the later growth period, the ditches should be dredged in time to eliminate stagnant water and waterlogging in order to ensure high quality and high yield. Fourth, the prevention and control of peanut diseases and insect pests: the main disease in the late growth stage of peanut is leaf spot, the peak of which is 20-30 days before harvest, and the occurrence of high temperature and humidity or continuous overcast and rain is more serious. You can choose 75% chlorothalonil wettable powder 600x liquid or 70% methyl thiophanate wettable powder 1000 times liquid spray control, spray once every 10 to 15 days, even 2 times for 3 times. For serious grub fields, 50% phoxim EC 1500 times liquid can be used for heap control, with 50 grams of medicine solution per hole, and the control effect of watering is better after irrigation. In addition, it should be paid special attention to that peanuts are oil crops, in the prevention and control of grubs, it is strictly forbidden to use 3911, methamidophos, 1605 and other highly toxic pesticides, so as not to affect human health.
