Banana seedling substrate and preparation method thereof

Abstract

The invention discloses a banana seedling substrate and a preparation method thereof. The banana seedling substrate comprises first turf, second turf, third turf, perlite, vermiculite and water-soluble organic fertilizers. The preparation method includes the steps: weighing the first turf, the second turf, the third turf, the perlite, the vermiculite and the water-soluble organic fertilizers for standby application according to weight ratio; screening the weighed first turf, the second turf and the third turf and disinfecting the turf at high temperature; mixing and uniformly stirring the turf with the perlite, the vermiculite and the water-soluble organic fertilizers. The substrate is treated at the high temperature, bacteria, fungi and viruses are killed, infection of dangerous diseases such as leaf spot diseases and bacterial soft rot diseases of bananas at a seedling stage is eliminated, insect sources and eggs are killed, insect damage is decreased, various weed seeds are further killed, the trouble of weeding is omitted, and time and labor are saved. The substrate is good in permeability and contains nutrient elements needed by banana growth, and fertilization is no longer considered.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a substrate for growing banana seedlings and a preparation method thereof. Background technique [0002] In the past, the traditional soil seedling cultivation, because the sterilization measures were not in place, the occurrence of leaf spot at the seedling stage was relatively common, seriously affecting the quality of banana seedlings, and some even brought dangerous and destructive diseases into the banana orchard through the banana seedlings, causing the banana The garden was destroyed once. Some dangerous pests live in the soil or lay eggs in the soil, and it is easy to bring the source of insects from the seedlings to the banana orchard, causing pests and losses. Weeding is time-consuming and labor-intensive work at the seedling stage, which increases costs. [0003] Traditional soil seedlings, the quality of the soil is uneven, and some soils ha...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of banana seedling raising substrate and preparation method thereof, aim at solving traditional soil seedling raising, sterilizing measures are not in place, and leaf spot disease at the seedling stage is relatively common, seriously affects the quality of banana seedlings, and more importantly, cannot Avoid the spread of devastating soil-borne diseases (such as banana wilt, banana bacterial soft rot), can not effectively avoid quarantine and dangerous pests, can not ensure smooth breathing of banana seedling roots, can not ensure balanced nutrition, resulting in poor growth, banana Problems such as low survival rate of seedling transplanting
