Matters needing attention in planting walnut in spring

Walnut is a very popular nut in the world, and it also has a certain planting area in China. It is distributed in almost every province in our country, and with the arrival of spring, the planting management of walnut is also onerous. There are many things to pay attention to when growing walnuts in spring. So the editor today brings you some notes on the planting of walnuts in spring. Let's take a look at it.

1. Fertilizer and water management

In spring, both young and adult walnut trees should be watered in time after the soil is thawed and before the walnut trees sprout. Replenish the water lost due to cold resistance in winter to promote the growth of new shoots. And proper watering in spring can also cool down, delay flowering time, and prevent from being harmed by late frost. Topdressing in spring is mainly based on nitrogen fertilizer, which is controlled well according to the different tree potential. The amount of fertilizer applied in spring reached 50% of that of walnut trees in the whole year. After fertilization for about a week, the fertilizer was watered again to improve the utilization rate of fertilizer.

2. Shaping and pruning

Shaping and pruning is an indispensable management work for walnut trees in spring. When pruning, we should control the pruning method according to the variety, tree potential, tree age, weather and other aspects. For example, early-maturing varieties have early fruiting time and high yield, but after fruiting, the loss of fertilizer and water is serious, so it is easy to think of it as a small old tree. Therefore, when we prune early-maturing varieties, we should focus on cultivating the shape of the tree and concentrate on nutrition. Then the precocious trees in the full fruiting stage should be cut back to improve their growth and enhance their fruiting time.

3. Prevent the cold in late spring

After the walnut tree enters the leaf expansion period, we should pay attention to observe the weather changes and make a good weather forecast. When the temperature drops to about 3 degrees, it is necessary to do a good job of heat preservation to prevent the new tips from freezing. During the flowering and fruiting period, if the temperature is zero, the freezing injury is aggravated, resulting in a decrease in yield. Therefore, we also need to prevent the phenomenon of late spring cold in spring, and smoking is the main measure to prevent late spring cold. When the temperature drops to zero, the grass ash should be lit in time to maintain the smoke state, which can effectively increase the temperature around the walnut tree.

4. Pest control

The common diseases and insect pests of walnut trees in spring are canker, aphids and so on. We should do a good job in clearing the walnut orchard and remove the fallen leaves, fruits, sick bodies and weeds in the orchard in time. Take it out of the orchard and burn it. Then disinfect the orchard regularly and use different disinfectants according to different diseases. Inhibit the activity of bacteria and reduce the incidence of diseases. Strengthen management and often check the growth of walnut trees. If you find anything abnormal, you should check it in time, and then deal with it according to the actual situation.

The above is a brief introduction to the matters needing attention in planting walnut in spring, and the management of planting walnut in spring is very important. Because this is directly related to the yield and quality of walnut, so we must pay attention to it. That's all for today's introduction. This article is for reference only.
