Melon-fruit-like vegetable internal-fixing grafting seedlings-growing method

Abstract

The present invention discloses an internal fixed grafting seedling-cultivating method for melons, fruit tree and vegetables. Said method is characterized by that it adopts the following steps: using stock and grafting seedling which are synchronously sowed and grown until 0.5-3 main leaves are grown; for solanum fruits, using knife to horizontally cut between their seed leaf and first main leaf or first main leaf and second main leaf; for melons, remaining one seed leaf and horizontally cutting; using steel needle, bamboo needle or plastic wire whose diameter is 0.4-0.6 mm and length is 8-12 mm as grafting needle, its two ends are respectively inserted into stock and grafting seedling, aligned and combined together, making careful management so as to implement its grafting work.

Description

technical field [0001] The invention belongs to the technical field of grafting and seedling cultivation of horticultural vegetable production, in particular to a method for grafting and seedling cultivation of melon and fruit vegetables, in which scion and rootstock are internally fixed by means of exogenous materials. Background technique [0002] Bacteria wilt, Verticillium wilt, root-knot nematode and other soil-borne diseases have occurred seriously in acidic soil or in the vast areas where soil acidification has been caused by long-term continuous cropping, improper use of chemical fertilizers or acid rain, and the loss ranges from 1 / 4. In serious cases, more than half of the harvest will be lost or even no harvest, which seriously affects the development of profitable agriculture. The above-mentioned disease prevention and control by pesticides or other methods have little effect. At present, varieties with strong disease resistance are ...

Problems solved by technology

However, in my country, except watermelon has a certain application area, other crops have little application. The main reason is that the amount of watermelon seedlings per mu is small, generally only about 600 plants / mu, so grafting requires less labor and the cost per unit area is relatively low. ; while the amount of tomato seedlings is 2500-3000 plants / mu, the grafting requires a lot of labor, and the relative cost is high, while the cultivation density of eggplant is higher, and the cost is higher

At present, the main grafting methods of vegetables and melons in my country are splicing, splitting, butting or socketing, which are troublesome to operate and low in efficiency, generally 300-500 plants / person. grafting is the main method, but the process of splitting is more complicated, the operation is inconvenient, and the grafting speed is relatively slow. At the same time, adventitious roots are likely to be produced at the interface of splitting seedlings in the later stage of cultivation, which directly affects the grafting effect; the speed and efficiency of socketing are improved compared with splitting. However, there are strict requirements on the size of the seedlings and the thickness of the stem during socketing, and there are certain difficulties in application. Moreover, there is a phenomenon of false survival of the socketed seedlings, and at the same time, the growth potential of the seedlings after survival is relatively weak, and it is easy to be infected with other diseases. Affect the effect of grafting

The operation of plugging and docking is inconvenient, and there are fewer applications in production, and the survival rate is not high, which seriously affects the popularization and application of grafting seedling raising technology in vegetable production.
