Are flowers afraid of drought or waterlogging?

Peanut is not a drought-resistant crop, and the drought tolerance of plants is slightly stronger than that of waterlogging. Long-term drought or waterlogging will reduce the yield and quality of peanuts. Therefore, in extremely dry weather, plants should be sprayed with water mist in time to improve the humidity in the field, and accumulated water should be discharged in rainy season. 0.2% potassium dihydrogen phosphate fertilizer solution should also be sprayed once during peanut flowering.

Is peanut a drought-resistant crop? Peanuts are not drought-resistant crops. The drought tolerance of plants is slightly stronger than that of waterlogging, but short-term drought and waterlogging will not have a significant impact on them. If the time is too long, the yield of peanuts will decrease, and the weight and quality of individual peanuts will also decrease.

Water management of peanuts Peanuts are relatively drought-tolerant plants, and water management is not needed in normal years. In case of extreme dry weather, when the plants are in flowering stage and the water content of the 0-30cm topsoil is lower than half of the normal water content, the peanut should be irrigated immediately.

When preparing soil by fertilizing peanuts, fertilizers such as organic fertilizer, pure nitrogen, phosphorus pentoxide and potassium oxide should be applied to the soil as base fertilizers. In the middle and late growth stage, potassium dihydrogen phosphate fertilizer solution with a concentration of about 0.2% should be sprayed to promote flower bud differentiation and improve seed setting rate.

Peanut pests and diseases Peanut infected with aphids, leafhoppers, thrips and other pests will spread virus diseases, stem rot and other diseases in a large area. Therefore, it is necessary to spray omethoate to kill the pests first, then clean up the diseased plants in the peanut field, and then spray drugs such as virus king, carbendazim and chlorothalonil evenly.
