Problems solved by technology

[0003] However, mulching technology also has certain limitations. In addition to the environmental problems that are not easy to degrade, due to its warming and heat preservation effect, it is easy to make the ground temperature too high in high temperature seasons and have adverse effects on crops, such as eggplant, tomato, sweet pepper and other vegetables. , in the middle and late stages of growth, the production of the root system tends to slow or stop and cause premature senescence, resulting in reduced yield

Embodiment 1

[0041] Example 1 (eggplant)

[0042] A compound material for promoting root growth and preventing premature aging of vegetables, comprising the following components in parts by weight: 90 parts of straw, 10 parts of vermiculite, 0.25 parts of enzyme bacteria, and 0.1 part of water-retaining agent.

[0043] Among them, the straw is crushed to a diameter of 1-4cm, the particle size of the vermiculite is 7-12mm, the expansion multiple is 8-12 times, and the water-retaining agent is polyacrylamide fine powder with a particle size of 0.85-2mm.

[0044] The above-mentioned components are fully mixed to obtain the compound material.

[0045] The composite material of this embodiment is used for greenhouse eggplant cultivation, and the steps are as follows:

[0046] (1) Grafting eggplant seedlings, planting the grafted seedlings on March 15;

[0047] (2) Lay the prepared composite material on the ground after planting and lay it with a thickness of 3cm;

[0048] (3) In late July, c...

experiment example 1

[0049] Experimental example 1 (eggplant)

[0050] A control experiment was carried out in an eggplant greenhouse of the Economic Crops Research Institute of the Hebei Academy of Agriculture and Forestry Sciences. The plot in the greenhouse was divided into two parts: the experimental group and the control group, and the same grafted eggplant variety (Yuanza 471) was planted with a planting density of 1600 plants / 667m 2 , double-stalk pruning, during the whole growth period, remove the leaves and branches below the first lateral branch, supply fruit growth with concentrated nutrients, promote early maturity, and harvest door soba in time. Except for the double-stem, all the other leaf buds and lateral branches are removed. For the retained branches, use plastic ropes to pull or hang them from the base of the branches, so that they can basically maintain an upright growth state, preventing the branches from being bent or falling down due to continuous fruiting. 18-20 single plan...

Embodiment 2-3 and comparative example 1-3

[0052] The composition and laying thickness of the composite material are shown in the table below, and the rest of the management is the same as in Example 1.

Abstract

The invention discloses a vegetable root growth promoting and premature decay prevention compound material, which is prepared from straws, enzyme microorganism, water-retaining agents, vermiculite or perlite. The invention further provides a method for using the compound material for culturing grafted vegetables. By covering the ground with the compound material with a certain thickness and combining the branch cutting or head changing treatment, the effect of obviously increasing the yield of the vegetables can be achieved.

Description

technical field [0001] The invention relates to the technical field of vegetable cultivation, in particular to a compound material for promoting root growth and preventing premature aging of vegetables and a method for cultivating vegetables using the same. Background technique [0002] Film mulching has the functions of increasing temperature, water retention, fertilizer retention, improving soil physical and chemical properties, increasing soil fertility, inhibiting weed growth, and reducing diseases. It is a commonly used technology in vegetable production and cultivation. [0003] However, mulching technology also has certain limitations. In addition to the environmental problems that are not easy to degrade, due to its warming and heat preservation effect, it is easy to make the ground temperature too high in high temperature seasons and have adverse effects on crops, such as eggplant, tomato, sweet pepper and other vegetables. , in the middle and late stages of its gro...
