Seed collection and seed storage of nursery land
The main results are as follows: 1. generally, when selecting nursery land, we need to consider the land with deep soil layer, high content of soil organic matter, low groundwater level, low saline-alkali content, leeward and sunny land, and sandy loam or light clay is suitable. Nursery land should be irrigated, irrigated and waterlogged.

Cultivation and management techniques of walnut trees during growing period
According to the significant changes in the characteristics of tree growth and development in walnut life, the growth period of fruit trees can be divided into: young stage, early fruit stage, full fruit stage and aging stage. In production, corresponding cultivation and management measures can be taken according to the characteristics of each growth and development period.

Effect of Grass mulching measures in Walnut Orchard
Grass mulching in orchard is an important technical measure to achieve high quality and high yield in dryland walnut orchard. Grass mulching in orchard can improve soil fertility, change groundwater, gas and thermal environment, restrain the growth of weeds, reduce the occurrence of diseases and insect pests and reduce the labor of hoeing, which can be used as walnut roots.

Reasonable intercropping cultivation model of walnut trees
Intercropping is an important cultivation mode. Reasonable intercropping can make full use of space, land and light energy, and improve economic benefits, especially the early benefits of young walnut orchards. The species and methods of intercropping are based on the principle that they do not affect the growth and development of walnut. According to

Introduction to the suitable pollination period and methods of walnut trees
1. Collect pollen and select strong adult trees locally or elsewhere, collect male inflorescences whose base is going to be pollinated (inflorescences change from green to yellow) or just beginning to disperse powder, and put inflorescences on clean sulfuric acid paper or newspaper in a dry, ventilated and non-direct sunlight room.

Pruning characteristics of walnut trees at different ages
1. The pruning period of walnut is different from that of other fruit trees. Because the dormant pruning of walnut after defoliation will cause "wound flow" by the wound, resulting in nutrient loss, tree weakness, and even branch death, it is not suitable to be carried out in winter. Walnut bleeding period

Attention to the Application of photosynthetic Micro-Fertilizer to Walnut trees
The picture shows that the photosynthetic micro-fertilizer of walnut is a kind of nutritious foliar fertilizer, which contains not only nitrogen, phosphorus and potassium essential for plants and many trace elements such as calcium, magnesium, sulfur, iron, manganese, zinc, aluminum and copper, but also photorespiration inhibitors (i.e. photosynthetic fertilizer). Has improved

Characteristics and control methods of walnut powdery mildew
The main results are as follows: 1. The distribution and occurrence characteristics are one of the common and important diseases in walnut producing areas in China. The disease seriously affects the yield and quality of walnut in the current year and the tree potential in the following year. The pathogen overwinters on fallen leaves or diseased shoots with a closed capsule. The temperature rises in the next spring, when I meet Rain Water, I close my bag.

Insect pests and control methods of walnut leaf borer, Chilo suppressalis
1. Distribution and damage symptoms are the main leaf-eating pests of walnut, distributed in North China, Northwest and Central-South China. The larvae bite on the walnut leaves and can eat up the whole tree leaves when they occur seriously. 2. Morphological characteristics and living habits belong to Lepidoptera, Pyralidae, also known as lignin.
