Matters needing attention in planting walnut in the latest spring

Walnut is a very popular nut in the world, and there are certain planting areas in China. Almost all provinces in our country have distribution, with the arrival of spring now, walnut planting management work is also heavy. Growing walnuts in spring is a lot to watch out for. So Xiaobian brought you the precautions for planting walnuts in spring today. Let's take a look at it together.

1. Fertilizer and water management

In spring, whether young or mature, water the trees once the soil thaws and before they sprout. Supplement the water lost due to cold resistance in winter and promote the growth of new shoots. And proper watering in spring can also cool down, delay flowering time, and prevent damage from late frost. Nitrogen fertilizer is mainly used in spring topdressing, and fertilizer is better controlled according to different tree vigor. The amount of fertilizer applied in spring reached 50% of the amount of fertilizer applied to walnut trees throughout the year. After fertilizing for about a week, water again to improve the utilization rate of fertilizer.

2. Shaping and pruning

Pruning is an indispensable part of walnut tree management in spring. When pruning, we should control the pruning method according to various aspects such as variety, tree vigor, age and weather. For example, although early-maturing varieties bear fruit early and produce high yields, they lose fertilizer and water seriously after bearing fruit, and they are easy to think of as small old trees. Therefore, when pruning early-maturing varieties, we should focus on cultivating tree shapes and concentrating nutrition. And then for the early mature trees in full fruiting period, we should carry out short truncation and retraction work to improve growth and enhance their fruiting time.

3. Prevent cold in late spring

After the walnut tree enters the leaf-opening period, pay attention to observing weather changes and make weather predictions. When the temperature drops to about 3 degrees, do a good job of insulation to prevent new shoots from being frozen. During its flowering and fruiting period, if the temperature is at zero, the freezing phenomenon will increase, resulting in a decrease in yield. Therefore, we should also prevent the occurrence of late spring cold phenomenon in spring. Generally, the measures to prevent late spring cold are mainly smoke. When the temperature drops to zero, it is necessary to ignite the ash in time to maintain the smoke state, which can effectively improve the temperature around the walnut tree.

4. Pest control

Spring walnut tree common diseases and insect pests are canker disease, aphids and so on. We should do a good job in clearing walnut orchards, timely removal of fallen leaves, fruits, sick bodies and weeds in the garden. Take it out of the orchard and burn it. Orchards should then be disinfected regularly, using different disinfectants according to different diseases. Inhibit the activity of germs and reduce the incidence of diseases. Strengthen management, often check the growth of walnut trees. If abnormal conditions are found, they should be checked in time, and then handled according to the actual situation.

The above is a brief introduction to the precautions for planting walnuts in spring, and the management of planting walnuts in spring is very important.
