Chinese walnut sowing and seedling breeding method

Abstract

The invention belongs to the technical field of agriculture, and particularly relates to a Chinese walnut sowing and seedling breeding method. The method specifically comprises the following steps: selecting seeds, airing the seeds, soaking the seeds, airing the soaked seeds, accelerating germination, preparing soil, and sowing the seeds. According to the invention, a nutrient solution prepared from mint, pine needles, seaweeds and glycine betaine is used for soaking the seeds, so that pollution of infectious microbes can be effectively prevented, and the germination of the walnut seeds can bepromoted. A culture medium prepared from fine sand, walnut green seedcases, artemisia argyi and the bagasse is used for accelerating germination, so that sufficient nutrients can be provided for thegermination of the walnut, invasion of bacteria can be inhibited, mildew and rotting of the walnut seeds can be reduced, and the germination rate of the walnut seeds can be improved. According to theChinese walnut sowing and seedling breeding method, the seed germination rate is high, the germination period is short, the walnut seedlings have good disease resistance, and the survival rate is high.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to a method for sowing and raising hickory seedlings. Background technique [0002] Hickory is a deciduous tree belonging to the family Juglandaceae and the genus Hickory. It is a unique economic tree species in my country. Pecan fruit, crispy and crispy, rich in protein, unsaturated fatty acids, vitamin E and other nutrients, has extremely high nutritional value and unique taste and flavor, and is a popular high-grade nut. [0003] With the improvement of living standards, the market demand of hickory nuts is increasing, and the cultivation scale is constantly expanding. Seedling cultivation is the key to the cultivation technology of hickory nuts; Hard, making it difficult to germinate. At present, people generally adopt growth-regulating liquid to soak seeds to promote the germination of walnuts; however, the seedling cultivation cycle of walnuts is long, and they are easil...

AI Technical Summary

Problems solved by technology

At present, people generally use growth-regulating liquid to soak seeds to promote the germination of walnuts; however, the seedling cultivation period of walnuts is long, and they are easily attacked by various bacteria during the seedling cultivation process, and mildew and rot occur.

For example, the method for sowing and raising seedlings of wild walnut disclosed in the document whose patent application number is 201310752735.5 uses clear water to soak the walnut seeds, and then the soaked walnut seeds are stored in sand, accelerated germination, and sowed; this patent is in the process of soaking, sand storage, and accelerated germination It only provides moisture for the germination of walnuts, and does not prevent the invasion of bacteria, and walnut seeds are prone to mildew and rot

Another example is a method for raising seedlings of pecans disclosed in a document whose patent application number is 201710631523.X. Solution 1 is used to soak the walnut seeds, and then solution 2 is used to accelerate germination of the soaked walnut seeds, and then the germinated walnuts and seed dressing agent Sowing after mixing; solution 1 can kill the worm eggs attached to the surface of the seeds, solution 2 can promote germination, and the seed dressing agent can inhibit the invasion of bacteria in the soil; although this patent has carried out prevention and control of bacteria in the seedling process, but in The germination process did not prevent the invasion of bacteria; the germination process is the main process for the walnut seed hole to absorb water and germinate. The walnut seed hole easily absorbs other bacteria while absorbing water, and mildew occurs
