Problems solved by technology

[0004] Fang Wei, Wang Kun and others experimented with the technical regulations of eggplant industrialized grafting and seedling cultivation, using the method of plugging or splitting, which has the disadvantages of low healing effect and underdeveloped root system.
There are very few domestic reports on eggplant using double-cut root grafting eggplant technology. Wang Bo, Chen Hao and others used double-cut root grafting eggplant technology for the first time in China. The survival rate of grafted seedlings is not high, and the emergence of seedlings is uneven. Therefore, the current eggplant industrial double-root grafting technology still has a low seedling raising rate, no relevant standards, and management measures after grafting. management, there is no technical system matching the factory industry

Embodiment 1

[0064] S1 raw material preparation (inoculation rootstock, scion)

[0065] The excellent rootstock variety of eggplant is Tolubamu, and the variety of scion eggplant is from Rexwang Company, such as 10-765, 602, 10-911.

[0066] Matrix nutrient ratio: Kleisman 416 matrix: perlite = 5:1, 416 matrix fiber length is 1-5mm, perlite particle size is 2-4mm.

[0067] S2. Inoculation rootstock, scion germination treatment

[0068] The rootstock Tolubam is very difficult to germinate, the germination rate is uneven, and the germination rate is not high. It is treated with Naitemin (product of Spanish Agricultural and Mining Company) and soaked in constant temperature hot water while stirring for 15-20 minutes. Soak the seeds at 0-5°C for 24 hours (stirring the seeds 4-5 times during the period), put them in the germination box for 24 hours, wash off the mucus of the seed coat with water, and soak the seeds again at 0-5°C for 24 hours with 800 times of Neitemin (stirring during the per...

Embodiment 2

[0109] The implementation method of L.1-L3 is consistent with the implementation method of S1-S3.

[0110] L4 Casing grafting method + double root pruning combination

[0111] L4.1 Grafting time: 25-28 days after the rootstock is transplanted, the diameter of the rootstock seedlings with five leaves and one heart or four leaves and one heart is 0.3-0.5 cm, and they are grafted on semi-lignified parts.

[0112] L4.2 Combination of grafting methods: casing grafting method + double root pruning combination

[0113] L4.2.1 Grafting combination: carry out when the rootstock seedlings have 4 to 5 true leaves. First rootstock seedling is excised above part (at least 5cm) from semi-lignified position, removes all true leaves and cotyledons, double cuts off rootstock root, only keeps a small amount of main root of stem base for subsequent use.

[0114] The method is simple and fast in operation, easy to master in technology, fast in grafting speed, high in survival rate, convenient for...

Abstract

The invention provides a factory eggplant double-root-cutting grafting seedling raising method. The method comprises the following steps of debugging equipment, preparing raw materials (inoculating rootstocks, scions and the like), carrying out matrix nutrition proportioning, carrying out germination accelerating treatment, sowing and transplanting, carrying out double-root-cutting grafting, healing, carrying out seedling hardening management, and standard finished products emergence. The production design is ordered, the production period is fixed for 80 days, automatic coordination of factory matching water, temperature, fertilizer and air is realized, high grafting survival rate, difficulty in excessive growth, neat and strong seedlings, consistent cultivation standard and strong seedlings are achieved, vegetable seedling quality is improved, soil harmful disease (eggplant verticillium wilt and bacterial wilt) resistance is remarkable, secondary infection prevention effect after plant formation is good, grafting seedling recovery time is shorter and faster, the survival rate is higher, the growth vigor is stronger, the root system is strong, the stress resistance is strong, the yield is high, the quality is better, and the technology breaks through the defects of the conventional grafting technology; and the grafting process is easy to decompose, suitable for industrialized seedling production and capable of reducing labor intensity.

Description

technical field [0001] The invention relates to a method for grafting and growing eggplant seedlings in industrial vegetable seedling cultivation, and belongs to the technical field of vegetable industrial seedling raising. Background technique [0002] Compared with the traditional seedling raising methods, industrial vegetable seedling raising has the advantages of saving seedling time, improving seedling quality, raising seedling efficiency, efficient unified management, and reducing production costs. It can achieve annual production without being affected by objective factors such as weather and environment. Continuous supply. Industrial grafting of vegetables is one of the methods to improve the quality of seedlings, and it is an effective way to overcome the root soil-borne diseases caused by conventional seedlings and improve the disease resistance of vegetables. [0003] In 1976, Japan invented root-cutting grafting and raising seedlings, which was widely used in pr...
