Special nutritive soil blocks for layering breeding of tomatoes

Abstract

The invention relates to special nutritive soil blocks for layering breeding of tomatoes. The implementation method comprises the following steps: taking 1 cubic meter of field soil, 4 kg of an organic fertilizer, 1 kg of an inorganic fertilizer, 1 kg of an insect-resist agent and 1 kg of a nutrient solution, mixing the five components uniformly, mechanically or manually pressing to make soil blocks of 10 cubic centimeters, stacking made soil blocks regularly, tightly covering the soil blocks with plastic films to enable pharmaceutical ingredients in the soil blocks to fully volatilize and diffuse, so that germs and injurious insects in the soil blocks can be killed , and the pest and disease damage to tomatoes in the nursery stage can be greatly reduced; besides, preparing to obtain the nutritive soil blocks by controlling the covering time to be not shorter than 7 days; placing the nutritive soil blocks properly before layering to allow the bottoms of the nutritive soil blocks to be fully wetted, therefore the bottoms of the nutritive soil blocks can be enabled to expand and fluff out, and the wetted surfaces of the nutritive soil blocks can be pressed on the tomato bushes. According to the special nutritive soil blocks for layering breeding of tomatoes, provided by the invention, the manually or mechanically prepared compressed soil blocks are rich in various nutritional ingredients and microelements, can uniformly supply nutrients needed by rooting of sprouts and growing of seedlings, can further promote vigorous growth of seedlings.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a special nutrient soil block for tomato branching propagation. Background technique [0002] Tomato press branch propagation is mainly used for the cultivation of autumn stubble tomatoes. Its main advantages are: first, it can directly grow seedlings in the tomato production moisture, effectively solving the problem of the shortage of heavy cropping tomato seedlings; , do not need to consider looking for other plots; the third is that the seedling breeding period is shortened by nearly 20 days, which effectively increases the tomato fruiting period and increases tomato production by nearly 3 layers. [0003] The usual method for raising seedlings by pressing branches is mainly to select healthy fork branches, press the fork branches on the ground at the position of 2-3 nodes later, and then dig 1-2 inch small ditches along the direction of the branches, fertilize and apply pest...

But the disadvantage is that it is time-consuming, sometimes it is difficult to control the amount of fertilization and pesticide application, which can easily lead to uneven emergence and large quality gaps, etc.
