Peanut management is a key period to determine the yield and quality of peanuts. It is necessary to put a good last step and strengthen the management of the field in the later stage to ensure the high quality, high yield and good harvest of peanuts. The main management techniques of peanuts are as follows:

Spraying fertilizer outside the roots. In the late growth stage of peanut, the root absorption capacity is weakened, and it is prone to defamation and premature aging. For example, when the phenomenon of de-fertilization occurs later, the root can be sprayed by the method: using 1%~2% urea aqueous solution or 2%~4% phosphoric acid The aqueous solution of potassium hydroxide is sprayed once every 5 to 7 days, and even sprayed 2 to 3 times. Protect the roots with leaves to achieve the goal of increasing disease resistance and increasing production.

Maintain proper soil moisture. The water requirement in the late growth stage of peanuts is not as good as in the medium term, but it still needs to be watered in case of drought. If the soil is dry, it affects the photosynthetic production of stems and leaves. However, the amount of water should not be too large, such as the soil is too wet, affecting the expansion of underground pods, and even rotten fruit.

Control pests and diseases. Peanut is susceptible to leaf spot, rust and aphid in the late stage of growth. Leaf spot disease can be controlled by spraying 70% mancozeb or 75% chlorothalonil 500 times. For the prevention of rust, 30 % of the rust- wet WP can be sprayed with 50 grams of water and 50 kg. The control of aphids can be controlled by spraying 3% acetamiprid emulsifiable concentrate 1000 times.

Harvest at the right time to increase pod yield and quality. Timely harvesting can increase peanut yield and quality. It should be harvested in time when most of the pods are ripe, in case of fruit, bud fruit, rotten fruit, etc.
