What are the key points to note when planting walnuts in spring?

Walnut is a very popular nut in the world, and it is also grown to some extent in our country. It is distributed in almost every province in our country. Now that spring has arrived, the planting and management work for walnuts has also become heavy. There are many things to note when planting walnuts in spring. So today the editor has brought you the key points to note for spring walnut planting. Let's take a look below!

1. Fertilizer and water management

In spring, whether they are young trees or adult walnut trees, after the soil thaws and before the walnut trees sprout, water them once in a timely manner. This replenishes the water lost in winter due to cold resistance and promotes the growth of new shoots. Proper watering in spring can also lower the temperature, delay flowering time, and prevent damage from late frost. When topdressing in spring, mainly use nitrogen fertilizer, and control the amount of fertilizer according to the differences in tree vigor. The amount of fertilizer applied in spring reaches 50% of the walnut tree's total annual fertilizer application. About one week after fertilizing, water once again to improve the fertilizer's utilization and conversion rate.

2. Training and pruning

Training and pruning is an indispensable management task for walnut trees in spring. When pruning, we should control the pruning method well according to the variety, tree vigor, tree age, weather, and other aspects. For example, although early-maturing varieties bear fruit early and have high yields, after fruiting they lose fertilizer and water seriously and are prone to becoming small old trees. Therefore, when pruning early-maturing varieties, we should focus on developing the tree shape and concentrating nutrients. Then, for early-maturing trees in the full fruit stage, carry out heading back and renewal pruning to improve growth vigor and enhance their fruiting time.

3. Preventing late spring cold

After walnut trees enter the leaf expansion stage, pay attention to observing weather changes and do a good job of weather forecasting. When the temperature drops to about 3 degrees, do a good job of heat preservation to prevent new shoots from being damaged by freezing. During their flowering and fruiting stage, if the temperature is at zero degrees, the freezing damage worsens, leading to reduced yield. Therefore, in spring we must also prevent the occurrence of late spring cold. Generally, the main measure to prevent late spring cold is smoking. When the temperature drops to zero degrees, promptly light grass ash and other materials and maintain a dense smoke state, which can effectively raise the temperature around the walnut trees.

4. Pest and disease control

Common pests and diseases of walnut trees in spring include canker disease and aphids. We should do a good job of cleaning the walnut orchard, promptly removing fallen leaves, fallen fruit, diseased and disabled plant parts, and weeds in the orchard. Take them out of the orchard and burn them. Then regularly disinfect the orchard, using different disinfectants according to different diseases. Inhibit the activity of pathogens and reduce the incidence of diseases. Strengthen management and frequently inspect the growth of walnut trees. If abnormalities are found, inspect them promptly, and then handle them accordingly based on the actual situation.

The above is a brief introduction to the key points to note for spring walnut planting. The management work for planting walnuts in spring is very important. Because it directly affects the yield and quality of walnuts, everyone must pay attention to it. That is all for today's introduction. This article is for reference only.
