Peanut clear trees can increase production

Peanuts are dicotyledonous plants, due to the cotyledon hypertrophy, difficulty in emergence. When the peanuts emerged, the two cotyledons were generally not excavated, and they were half unearthed under conditions of light sowing and loose soil. Clear tree is when the peanut Qimiao, the soil of the base of the seedlings open, so that the two cotyledons exposed on the ground, clear tree is an important measure of peanut production. The clear tree exposes the two cotyledons out of the ground and promotes the growth of the first pair of lateral branches, because the first pair of lateral branches of peanuts grows from the cotyledon leaves, and the growth of the second pair of lateral branches is strong. The two pairs of lateral branches are strong. And the second branch occurred on it and constituted the main body of the peanut plant, which is also the main part of the fruit. The number of fruits on the first and second pairs of side branches accounted for more than 70--90% of the total fruit of the whole plant. Therefore, the production of these two pairs of lateral branches to promote early robust development is an important way to obtain high yield. By clearing the tree, the first pair of lateral branches are liberated, so that it is directly exposed to sunlight as soon as it is born, which accelerates development and facilitates the development of the second pair of lateral branches and the differentiation of the flower buds at the base. The clear tree can also promote the development of the root system, and the stems are stoutly short in the internodes. The effective flowering amount in the early stage is increased, the solid range is concentrated, and the number of full fruit is large. Clear trees promoted robust plants and deep roots, and improved drought resistance. Clear trees can also reduce the damage of weeds and aphids. After clearing trees, they can increase production by about 20%. It is advisable to clear the trees in the basic Qimiao time so that Qimiao will clear one piece. Early in the morning, the seedlings were too small and the resistance was poor, causing the young shoots to dry and causing dead seedlings. In late Qing and late evening, the first pair of collaterals grew weakly, and flower bud differentiation was affected. The depth of clearing was the standard for exposing two cotyledons. Be careful not to damage the cotyledons so as not to affect the development of the first pair of collaterals. Before qingqian, first cultivating again, do not cultivate within half a month of clearing, otherwise it is necessary to bury the ploughed soil back, about half a month after clearing the tree, when the first pair of side branch fruit needle has been buried, the second pair of lateral branches When the needle grows, deep burrows are buried and soil is used to welcome the needle. Kinds of peanuts in the lyrical watering ground are so shallow that they do not need to be cleaned. Peanut cultivation of peanuts, when ploughing flat ridges, will play a clear role.
