Fruit vegetable seedling culture method in winter and spring

Abstract

The invention discloses a fruit vegetable seedling culture method in winter and spring, which comprises the steps of: seedling bed building, seedling bed fertilization, nutrition soil preparation and seeding. In the seedling bed building step, north-south geosynclines with the depth being 0.4 to 0.6m, the width being 1.3 to 1.7m and the length being 5.0 to 8.0m are dug in a position with sufficient light illumination in a daylight greenhouse or a greenhouse, heat insulation materials are adopted at the periphery of the inner wall of the geosynclines to be used as heat insulation inner liners, rice hulls with the thickness being 4 to 6cm are paved at the bottom of the geosynclines, a heat insulation cover plate is arranged at a notch, and a box type seedling bed is formed. The fruit vegetable seedling culture method in winter and spring aims at solving the problems that in the cold-season seedling culture in winter and spring, the facility is simple, heating equipment is lack, the cold damage is easy to occur, and the seedling culture quality and the success ratio are low. According to the invention, the seedling culture box type seedling culture is adopted, and the seedling bed night temperature is improved by 5 to 7 DEG C. According to the seedling culture method, the occurrence of cold damage and freeze damage can be effectively prevented in cold season, the strong seedling rate is improved to a value higher than 90 percent, and in addition, the effects of environment protection, energy saving, low cost and easiness in control to the technology are realized in the seedling culture process.

Description

technical field [0001] The invention relates to a method for growing seedlings of fruit and vegetables in winter and spring. Background technique [0002] The seedling cultivation of winter and spring fruits and vegetables mainly refers to the seedling cultivation carried out from November to February. During this period, the seedling cultivation is in an environment with low temperature, short sunshine and weak light. facilities for seedling cultivation. Due to the high investment cost of heating facilities, more than 90% of the seedlings in actual production are carried out without adding heating facilities. Fruit and vegetable vegetables are a kind of vegetables that like temperature, and flower bud differentiation is also carried out in the seedling stage, so temperature has become the main limiting factor for fruit and vegetable seedling cultivation, especially in winter and spring. Peppers, eggplants, cucumbers and other fruits and vegetables in early spring have the...

AI Technical Summary

Problems solved by technology

Peppers, eggplants, cucumbers and other fruits and vegetables in early spring have seedlings in the middle of winter, with low temperature, short sunshine, and insufficient light, which are not good for seedlings and can easily cause seedling failure.

Raising seedlings under the condition of non-heating facilities, due to the poor heat preservation effect, especially the low night temperature, not only inhibits the growth of seedlings, but also affects the flower bud differentiation of seedlings, reduces the quality of seedlings, and the rate of strong seedlings is less than 50%.
