Problems solved by technology

[0003] There are many techniques for raising seedlings and planting of relevant walnuts in the prior art, mainly based on grafting, mainly because the walnut seed shell is hard and absorbs water slowly, especially the seeds of spring sowing, if directly sown with dry seeds, the germination rate is relatively high. Low; grafting is asexual reproduction, the DNA of the parent and offspring is basically identical, so the probability of evolution will be very small, while seed breeding is sexual reproduction, which is conducive to gene exchange and will produce offspring more suitable for the environment , the ability to adapt to the external environment is stronger than that of asexual reproduction. Therefore, it is the only way for future technological development to develop a treatment method for seeds before sowing to improve the germination rate of walnuts.

Embodiment 1

[0012] Embodiment 1: a kind of processing method of walnut seed before sowing, comprises following operation, carries out before sowing 11d, and the walnut seed of spring sowing, thick shell is processed: first walnut seed is placed in the soaking bucket, after pouring After soaking in hot water at 40-50°C for 24 hours, take it out and place it in a cool and ventilated place to dry for 1 day, then take it out, put it in warm water at 20-30°C for another 24 hours, take it out and dry it for 2 days; use water content of 15 ~20% of the river sand is stored in sand. When storing the sand, first sterilize the river sand, and then spray it with sterile water to infiltrate it. First, spread a layer of 2cm wet river sand on the bottom of the container, and slit the tip of the walnut seeds , spread a layer of walnut seeds on the bottom river sand, with the tip pointing up when laying, cover this layer of walnut seeds with river sand with a thickness of 3~4cm, another layer of walnut see...

Embodiment 2

[0013] Embodiment 2: a kind of processing method of walnut seed before sowing, comprises following operation, carries out before sowing 10d, the walnut seed of spring sowing, thick shell is processed: first walnut seed is placed in the soaking bucket, after pouring After soaking in hot water at 40-50°C for 24 hours, take it out and place it in a cool and ventilated place to dry for 2 days, then take it out, put it in warm water at 20-30°C for another 24 hours, take it out and dry it for 2 days; use water content of 15 ~20% of the river sand is stored in sand. When storing the sand, first sterilize the river sand, and then spray it with sterile water to infiltrate it. First, spread a layer of 2cm wet river sand on the bottom of the container, and slit the tip of the walnut seeds , spread a layer of walnut seeds on the bottom river sand, with the tip pointing up when laying, cover this layer of walnut seeds with river sand with a thickness of 3~4cm, another layer of walnut seeds,...

Embodiment 3

[0014] Embodiment 3: a kind of processing method of walnut seed before sowing, comprises following operations, carries out before sowing 9d, and the middle and thick shell walnut seed of spring sowing is processed: first walnut seed is placed in the soaking bucket, after pouring 40 After soaking in hot water at ~50°C for 24 hours, take it out and place it in a cool and ventilated place to dry for 2 days, then take it out, put it in warm water at 20~30°C for another 24 hours, take it out and dry it for 3 days; use a water content of 15~ 20% of the river sand is stored in sand. When storing the sand, first sterilize the river sand, spray and infiltrate it with sterile water, first spread a layer of 2cm wet river sand on the bottom of the container, and slit the tip of the walnut seeds. Spread a layer of walnut seeds on the bottom river sand, with the tip pointing up when laying, cover this layer of walnut seeds with river sand with a thickness of 3~4cm, another layer of walnut se...

Abstract

The invention relates to the technical field of fruit tree cultivation, and discloses a method for treating walnut seeds before sowing. The method comprises the following steps that walnut seeds are placed in a seed soaking barrel to be soaked with hot water, fishes out to be dried at the shady, cool and ventilated place for 1-2 d, soaked with warm water, fished out and dried for 2-3 d; the walnut seeds are stored with wet river sand layer by layer, 7-9 layers are laid all together, and the uppermost layer is the sand layer; a container is placed in a greenhouse, hothouse or plastic house, the walnut seeds are sprayed with water one time every 12 h, and sand storage is kept for 3-7d. According to the walnut seeds treated through the method, at the eighth day, the germination rate reaches 80%; at the fourteenth day, the germination rate reaches 85% or more, operation time is short, the effect is achieved rapidly, the germination rate is high, operation is convenient, and the method is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for treating walnut seeds before sowing. Background technique [0002] Walnut is the king of high-grade edible woody oil in the world. It is rich in nutrition, and its food can strengthen brain and intelligence, promote blood circulation and remove blood stasis, moisten dryness and reduce phlegm, moisturize skin and beautify, and prolong life. Therefore, it is necessary to grow a large amount of walnuts to meet the increasing consumption demand. [0003] There are many techniques for raising seedlings and planting of relevant walnuts in the prior art, basically based on grafting, mainly because the walnut seed shell is hard, water absorption is slow, especially the seeds of spring sowing, if directly sown with dry seeds, the germination rate is relatively high. Low; grafting is asexual reproduction, the DNA of the parent and offspring is basically identic...
