Benefits of technology

This patented technology improves how well it can grow crops with walnuts that have been treated for disease or damage caused by weather conditions such as rainwater overhauled them during winter months. By doing this, they will be able to produce more nutritious food while still being resistant against harmful microorganisms like bacteria and fungi.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the success rates for transplantation from poorly-planted high nutness seeds such as yarnosukeki or other types of walnuts that have been developed through traditional ways like hand pickling techniques.

Embodiment

[0014] Embodiment: the concrete steps of the grafting method of excellent product walnut are as follows:

[0015] (1), natural conditions: northwestern Hubei;

[0016] (2), cultivate rootstock:

[0017] Select walnuts from Northwest Hubei as rootstocks for grafting, use 200 catties of dry walnuts per mu, 120 catties of compound fertilizer per mu, and 2,000 catties of farmyard manure as base fertilizer. Drill sowing in mid-October, and seedling management after emergence in March of the next year. The ground diameter is 0.8-1.2 cm, and the density is controlled at 6000 plants / mu;

[0018] (3), seedling grafting:

[0019] a. Collection of scions of good varieties: From early May to mid-month, collect branches of high-quality walnut varieties, with a thickness of 0.8-1.5 cm, strong growth, full buds, and no pests and diseases. 2-4 branches full of buds are used as scions;

[0020] b. Grafting date and weather: Grafting will be carried out from May 10th to June 20th. The grafti...

Abstract

The invention provides a grafting method of a superior walnut, which comprises the specific steps as follows: (1) cultivating a stock: selecting an ordinary walnut variety, wherein the sowing time is in October to December, the density is controlled at 5500-6000 plants per mu, and the basal diameter is 0.8-1.5cm; (2) grafting seedlings: a, collecting braches of the superior walnut and spring tips with the thickness of 0.8-1.5cm and cutting into the branch segment with the length of 12-15cm and 2-4 full buds left for scion; b, the grafting time lasts for 5-7 months, and the grafting air temperature is at 28-30 DEG C; and c, the grafting method adopts a budding method, and the grafting part is at 10-15cm from the stock to the ground and is wrapped by a plastic film; (3) later-period management: cutting the stock and protecting the bud after grafting for 10-20 days, and controlling the pests and disease and protecting the buds after 30 days; and (4) selling the seedlings: the seedlings are removed and sold step by step in the late October. By adopting the grafting method, the grafting survival rate of the walnut seedlings is improved to 85-90%, and the grafted walnut seedling begins to bear fruits after three years and achieves high yield after five years after being transplanted.
