Problems solved by technology

[0003] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: the traditional technology of grafting and growing seedlings in tomato plugs tends to cause excessive growth of grafted seedlings due to factors such as the plugging seedling raising environment, resulting in a decline in the quality of grafted seedlings, mainly manifested as Grafted seedlings have poor rooting ability after planting, weak growth potential, high rate of deformed fruit (mainly caused by poor differentiation of flower buds at seedling stage), poor disease resistance, and low yield

Abstract

The invention provides a method for cultivating healthy grafting seedlings of tomatoes. Turf, vermiculite and pearlite are evenly mixed according to the volume ratio of 6:3:1 to prepare seedling cultivating substrates, and the operation of raising seedlings by grafting in plug trays is performed; stock and scions are sown in the same period, and 5-8 ml of a potassium phosphite aqueous solution with the concentration being 50 mg.kg-1 is applied to each tomato seedling from the time when the stock buds to the time when cotyledons are expanded; 8-10 ml of a prohexadione-calcium aqueous solution with the concentration being 10 mg.kg-1 is applied to each tomato seedling from the time when the tip of a first interior leaf of each scion is exposed to the time when one leaf and one core are formed; 8-10 ml of a prohexadione-calcium aqueous solution with the concentration being 20 mg.kg-1 is applied to each tomato seedling when the length of a third main leaf is 1 cm after grafting; 12-15 ml of a chitosan aqueous solution with the concentration being 500 mg.kg-1 is applied to each tomato seedling when the length of a fourth main leaf is 1 cm after grafting. The grafting seedlings cultivated through the method are superior to conventional grafting seedlings cultivated in plug trays in the aspects of root activity, sound seedling index, flower and bud differentiation, disease resistance, yield and the like.

Description

technical field [0001] The invention relates to a method for cultivating tomato seedlings, in particular to a method for cultivating healthy grafted tomato seedlings, belonging to the technical field of vegetable seedling cultivation. Background technique [0002] Tomato plug grafting has been widely used in production. Plug seedlings use light materials such as peat and vermiculite as seedling substrates, adopt precision seeding, and a modern seedling raising system that grows seedlings at one time. The traditional plug seedling technology has the advantages of energy saving, labor saving, labor saving, seedbed area saving, seed saving, long-distance transportation and standardized seedling management technology. Modernization and mechanization, the commercialization of seedling supply has been realized. [0003] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: the traditional tech...
