The latest course of cultivation techniques of Carya cathayensis

Carya cathayensis, also known as small walnut, belongs to the deciduous tree of the genus Carya. Many people will confuse pecans with American pecans. In fact, pecans are very different from pecans. The shape of pecan is small round, the root fruit is long, and pecan is rich in protein and essential fatty acids. So how to grow pecans? Today, the editor brings you the cultivation techniques of hickory. Let's have a look.

1. Land selection and preparation

Carya cathayensis is a kind of plant that likes temperature and humidity, so when we choose the planting place, we should choose the place where the climate is moderate, the water is abundant and the terrain is high. And the soil is rich in humus, good drainage and irrigation, moderate pH, pecan orchard can not be built on a steep hillside. After selecting the land, we should prepare the soil in time, plough the soil and disinfect it. However, because pecans do not require much light, and the growth period is longer, so we do not have to use the method of bulk soil preparation.

2. Timely planting

After soil preparation, it will begin to be planted. Carya cathayensis is planted by sowing and artificial cultivation of seedlings, but the growth time of the sowing method is too long. Therefore, the method of artificial cultivation of seedlings is generally used. when selecting young trees, it is necessary to observe the growth of young trees and choose young trees with developed roots and harmless roots. Dig the planting hole, put the young trees in the center of the planting hole, and then apply enough rotten farm manure and add an appropriate amount of phosphate fertilizer. The planting time of hickory seedlings is the most suitable when the temperature is low in autumn and winter every year.

3. Young tree management

After successful planting, the seedlings of Carya cathayensis are relatively fragile, so we should strengthen the management of young trees and promote the growth of young trees. After planting, weeding should be done once in time in summer, and the number of weeding should not be less than twice a year. Then according to the situation of young trees, topdressing can be carried out with weeding work, fertilizer is mainly available nitrogen fertilizer, phosphorus and potassium and other fertilizers can be added appropriately. The dosage should be controlled according to the planting quantity, and we can increase the dosage appropriately according to the tree-shaped long hair to strengthen the growth of walnut trees, provide adequate nutrition for growth and prevent malnutrition.

4. Shaping and pruning

The tree shape of Carya cathayensis is relatively tall when it grows up, and it will have a certain height in the period of young trees. Therefore, the work of shaping and pruning begins in the early stage of young trees, and the pruning of young trees is mainly light pruning, retaining fruit mother branches and early fruiting time. The purpose of pruning is to improve the permeability of orchards and increase the light area of fruit trees. Early pruning should try to retain the upper part of the fruit tree at least, cut off the treatment of too dense and too long. The trimming mouth should pay attention to do a good job of disinfection to prevent infection from causing diseases and insect pests and leading to decay.

The above is a brief introduction to the cultivation techniques of Carya cathayensis. The cultivation of pecans has a certain area in our country. Pecans have gradually entered people's field of vision, but because the harvest period of pecans is very long, and the planting technology is not mature, so we must carefully consider before planting. That's all for today's introduction. This article is for reference only. I hope it can help you all.
