When do walnuts usually grow? What are the benefits of scattered planting?

Walnut is a kind of nut with high nutritional value. It is often said that eating walnut is beneficial to intelligence, because the internal structure of walnut is similar to that of human brain. Walnuts are planted in many places in China, and trees that have been growing for more than a hundred years can still maintain a high yield. When do walnuts usually grow? What are the benefits of decentralized planting?

When do walnuts usually grow?

Generally speaking, it is the season for planting trees from the "dormant" and "semi-dormant" state of walnut seedlings (the Beginning of Autumn) to next year (the second year) before walnut seedlings sprout. But the sooner you plant it at this time, the better. Why? Because during the period of late autumn and early winter, whether in the south or north of China, the soil temperature (ground temperature) is mostly above 15 ℃. The root system of walnut seedlings continued to move when the ground temperature was higher than 15 ℃. When the tree is planted at this time, the root system of the walnut seedling will soon plunge into the soil. When the temperature rises in spring, the moisture and nutrients in the soil will quickly pass through the root system to the tree body, and the tree seedling will grow fast, flourish and grow strong. If planted in spring, the temperature rises quickly, and the tree is eager to sprout and need water and nutrients, but at this time the roots of the seedlings have not yet been rooted in the soil and cannot be supplied, and many seedlings die as a result of "cutting off". Even if he does not die, he is still in a state of "undead and inanimate" for a long time, and there is no growth at all. So we often say: planting trees in autumn is a dream, and planting trees in spring is a disease.

What are the advantages of scattered planting of walnuts?

1. Keep ventilated and transparent. Walnut is a light-loving tree species, which can bear a large amount of fruit and high yield in the sunny, well-ventilated, warm and cool climate. If the forest planting is adopted, the canopy is connected to each other, the light in the canopy is weak, the ventilation is poor, the leaves in the canopy are few, thin, small, easy to fall early, the inner chamber bears little or no fruit, and the fruit is only distributed on the branches outside the canopy. The yield per plant and the yield per unit area are 20% and 40% less than those of scattered planting.

2. Do not fight for farmland soil. Scattered planting of walnut trees can make full use of scattered open spaces such as field head, land edge, gully slope, gap land, village side and courtyard, without competing with farmland. At the same time, the environmental conditions of scattered planting are also conducive to the growth and development of walnut trees, so high yield can be obtained.

3. The unit yield has been increased. The scattered planting walnut tree has high yield per plant, a wide range of suitable planting area and a large total planting area. When scattered planting, it can be planted on small plots of land that are not suitable for planting crops, such as field head, land edge, gully slope, gap land, open space next to the village, etc., and can be planted in all available spaces. The number and row spacing of planted plants are not limited, but the distance between two adjacent plants should not be less than 10 meters.

4. Restrain the occurrence of diseases and insect pests. Scattered planting had a certain inhibitory effect on the occurrence and spread of walnut diseases and insect pests and promoted the high quality and high yield of walnut.
