Ecological conditions for the growth and development of walnut
The adaptability of different walnut species and varieties to precipitation is very different. The annual precipitation in the distribution area of walnut is 800mm and 1200mm, while the early-bearing walnut is easy to get sick when the precipitation is more than 62.00mm. Walnuts are resistant to dry air, but to soil.

Pre-sowing treatment of walnut seeds
The dried seeds must be treated with appropriate measures before sowing in order to facilitate germination and shorten the germination period. The seeds after sand storage can be sown directly, but it is better to accelerate germination and then sow. (1) soak seeds in cold water before sowing in spring. Soak dried seeds in cold water.

Sowing methods of Walnut planting
The main results are as follows: (1) in order to facilitate the grafting operation, the wide and narrow row method is often used to cultivate the rootstock seedlings, with a wide row of 60 cm, a narrow row of 40 cm and a plant spacing of 15 cm. Those who only cultivate seedlings without grafting can be denser appropriately, with a row spacing of 20cm x 40cm. (2) it should be watered once before irrigation and sowing.

Grafting preparation of conventional Seedling techniques of Walnut
The main results are as follows: 1. The excellent varieties were selected as the mother tree of ear picking, and the nursery was established. Cutting from the harvest nursery can ensure the purity of the variety. The mother tree should have pure varieties, strong growth and no diseases and insect pests. After receiving and collecting, it is necessary to mark it to prevent confusion, because

Seedling Management of Walnut Seedling
Walnut seedlings began to emerge about 20 days after spring sowing, and all emerged in about 40 days. During this period, the seedling emergence was checked every day. After the seedlings were unearthed, the plastic film was cut open with a knife in time to prevent scalding seedlings. At the same time, the opened plastic film was buried strictly in wet soil. Strengthening seedling management is to cultivate strong seedlings.

Management of walnut seedlings after grafting
There are only a few months from May and June to October when the grafted seedlings come out of the nursery. In order to ensure the robust growth of grafted seedlings and cultivate high-grade seedlings, it is necessary to strengthen management. 1. Check survival and replacement of walnut buds after 1 week, check whether they are alive and fresh.

Brief introduction of cactus flower seat and introduction of flower birth
The primitive species of cactus-the leaf cactus has differentiated inflorescences, that is, each flower has a separate pedicel. Other kinds of flowers grow directly on the stem. Sometimes several flowers are extracted from the same thorn seat, such as the genus Longshengzhu, Reed and Fairy finger, and so on.

Seedling emergence, grading and Storage of Walnut seedlings
In cold winter areas, the seedlings are taken out of the nursery before freezing after falling leaves. The emergence of seedlings from the nursery is an important part of raising seedlings. The drawing plan should be worked out according to the needs, and the nursery should be released in batches according to the variety and planting needs and the situation of sale, so as to avoid coming out of the nursery, storage, transportation, etc.

Walnut orchard selection
The selection of walnut orchard is directly related to the success or failure of pollution-free production of walnut and its economic benefits. To achieve the goal of early fruit, high quality, high yield, high efficiency and no pollution as far as possible, we should choose the land with flat terrain, deep soil, fertile soil, leeward to the sun and convenient transportation.

Specific contents of walnut orchard planning
Due to the wide range of walnut adaptation, the site selection of the garden is not very strict, and the planning of the garden is extensive. As long as we carry out scientific planning according to the topography and climate characteristics of a certain area, we can weaken or eliminate the unfavorable factors in the construction of the garden, which is beneficial to the production and management in the future.
