Suggestions for the planting industry under the walnut forest in Sichuan Province

The main problems in the development of walnut plantation in Sichuan Province and the main problems that should be paid attention to are training and improvement of planting techniques; adjustment of intercropping crop structure to promote the development of walnut industry; government attaches importance to the overall development plan; knowing the understanding of walnut planthoppers for undergrowth crops There is inhibition, etc., the specific small series will be explained in detail below.

1 Training, improve planting techniques

Strengthen the training of farmers' traditional planting techniques in the intercropping of walnuts under the forest, improve the yield, quality and commerciality of crops, and promote the poverty alleviation of the walnut industry.

2 Change concepts, adjust intercropping crop structure, increase land added value, and promote the development of walnut industry

Breaking the intercropping crops mainly adopts the traditional cultivation mode of corn and rape, and studies the suitable planting pattern of walnut.

2.1 Research and development of "forest food" model

In the geographical and market advantages of Chengdu, Mianyang and other places, research and development of suitable varieties, varieties and cultivation techniques of landscape red buckwheat planted in young walnut forests in the region. Using the characteristics of walnut germination in May, the development of adult walnut forest in early spring is suitable for the cultivation of red buckwheat planting mode, improving the light, heat, water and land utilization rate of walnut forest.

2.2 Research and development of "forest medicine" model

Study and develop the types, varieties and cultivation techniques of Chinese herbal medicines suitable for planting in the area under drought and cold mountainous areas, and make full use of land resources to study and develop the walnut industry.

2.3 Research and development of "forest fertilizer" model

Sichuan is a suitable area for spring broad bean, and broad bean has a nitrogen-fixing effect, which can improve the fertility of walnut forest and alleviate the problem of chemical fertilizer pollution. Therefore, it is possible to study the cultivation techniques of spring broad bean and other legume cultivation under walnut forest.

2.4 Research and development of "forest grass" mode

Animal husbandry is also a major industry. Therefore, we can use the land resources of walnut forests to study and develop high-quality pasture planting patterns, such as planting oats and alfalfa, which can improve soil fertility and provide forage for the breeding industry and improve walnut land. Additional value.

3 The main problems that should be paid attention to in the development of walnut forests

3.1 The government attaches importance to the overall development plan

The government should do a good job in guiding, planning, in-production services, post-production market cultivation, promotion work, cultivation of technology, sales of the market, and promote the income and stability of the planting industry to promote the development of the walnut industry.

3.2 Juglans mandshurica inhibits understory crops

Because walnut branches, leaves and roots secrete a chemical toxin of walnut (pepper), the cell wall tissue will be destroyed after absorption by other plants. In severe cases, the plants will wither and die, and the walnut (pecan) has herbicidal action. In the short term, it will inhibit the growth of other plants, and in the long term it will inhibit the growth of walnuts themselves.

3.3 Walnut and undergrowth crops compete for fertilizer, water, light

Water, fertilizer and light are essential for plant growth. Therefore, planting economic crops under the walnut forest should pay attention to the competition between the walnut and the forest under the fertilizer and water (wrong peak). In short, we should make good use of resources and focus on complementary advantages. .
