Detailed Explanation of Spring Walnut Planting Precautions
Walnut is a very popular nut in the world, and it is also grown to a certain extent in our country. It is distributed in almost every province in our country, and now that spring has arrived, the planting and management work for walnuts has become heavier. There are many things to pay attention to when planting walnuts in spring. So today, the editor has brought you the precautions 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, they should be watered once in time. 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 the flowering time, and prevent damage from late frost. When topdressing in spring, nitrogen fertilizer is mainly used, and the amount of fertilizer should be controlled according to the different tree vigor. The amount of fertilizer applied in spring reaches 50% of the walnut tree's annual fertilizer application. About a week after fertilizing, water once again to improve the fertilizer use and conversion rate.
2. Shaping and Pruning
Shaping and pruning is an indispensable management task for walnut trees in spring. When pruning, we should control the pruning method 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 bearing fruit they lose fertilizer and water seriously and are prone to becoming small old trees. Therefore, when pruning early-maturing varieties, we should focus on cultivating the tree shape and concentrating nutrients. Then, for early-maturing trees in the full fruit stage, short cutting and renewal pruning should be carried out to improve growth and enhance their fruiting time.
3. Preventing Late Spring Cold
After the walnut tree enters the leaf expansion stage, pay attention to observing weather changes and do a good job in weather forecasting. When the temperature drops to around 3 degrees, insulation work should be done well to prevent new shoots from being damaged by freezing. During its flowering and fruiting stage, if the temperature is at zero degrees, the freezing damage will worsen, leading to a decline in yield. Therefore, in spring we must also prevent the occurrence of late spring cold. Generally, the measure to prevent late spring cold is mainly smoking. When the temperature drops to zero degrees, promptly light grass ash, etc., and maintain a dense smoke state, which can effectively increase the temperature around the walnut trees.
4. Pest and Disease Control
Common pests and diseases of walnut trees in spring include canker disease, aphids, and others. We should do a good job in cleaning the walnut orchard, promptly removing fallen leaves, fallen fruit, diseased and residual bodies, and weeds in the orchard. Take them out of the orchard for burning. 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 abnormal conditions are found, inspect them in time, and then handle them accordingly based on the actual situation.
The above is a brief introduction to the precautions 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.
