Apricot tree autumn tube is the key
Apricot trees are the first fruit trees in spring, and they are the first flowers. The nutrients needed for the formation of flower organs are achieved by the accumulation of tree bodies in the first year of autumn. Therefore, the autumn management is good for the flower structure and fruit setting of Hunchun. A decisive role. Apricot autumn tube should grasp the following three points: First, thinning and short cut. Apricot trees are strong and happy tree species, and their own growth is very strong, it is easy to form a competitive growth and the resulting parts move out. This is very unfavorable for the formation of strong flowers and the results, so it should be in the autumn tube after fruit harvest, the result tree is sparse Lord, adopting a pruning method based on sucking large branches and depressing tree heights to implement short cuts, promotes new branches on the lower part and inner part, and forms short fruit branches and bouquet-like fruit branches. Of course, attention should be paid to maintaining the main branches of the reserved branches to open the light path evenly, and the individual branches that can be left standing upright can be pulled, dropped, or otherwise supported and changed. Skirts, sick branches, and dense branches can be removed together. Second, fertilization and irrigation. In the autumn, apricot can be applied to 50 to 100 kg of urea nitrogen or 30 to 50 kg of urea per 667 m2 of land, and the appropriate amount of phosphorus and potassium fertilizer can be applied to plant a large tree. 5 kilograms, after the application of rain is good, if the fall drought is serious, can be in August to September to strive for irrigation. But pay attention to the roots under the tree can not be long bubble, bubble for a long time easy to hurt the root. Third, pest control and protection of leaves. The leaves are the fruit trees that produce nutrients. The complete thick leaves are the guarantee of the results of the apricot trees and generally do not attract people's attention. Futian hot and autumn drought occur from time to time. It is easy to provoke red spiders to spread, or there are continuous autumn leaching in late autumn. It is difficult to guarantee the differentiation of flower buds caused by defoliation diseases, so it is necessary to conduct regular observations in the fall. It can be used to spray insecticides, prevent diseases, and protect the leaves. In addition, adding 3% urea is more beneficial to the tree.
