Polyvinyl chloride micro-ecological agricultural plastic masterbatch and seedling tray made of it

Abstract

The invention provides microecologically agricultural polyvinyl chloride plastic masterbatch and a seedling growing tray prepared from the same. The masterbatch is prepared from components in parts by weight as follows: 10-40 parts of polyvinyl chloride, 15-25 parts of bentonite, 20-30 parts of kaolin, 10-60 parts of calcium carbonate, 0.1-1 part of a catalyst, 0.1-5 parts of a compatilizer, 0.5-2 parts of a stabilizer, 0.5-5 parts of a lubricant and 0.5-5 parts of mixed probiotics. The prepared seedling growing tray is well formed, is high in strength, not prone to deformation and easy to recover and can be repeatedly used, and the cost in a seedling raising process can be reduced; the added nanoscale bentonite, kaolin and calcium carbonate have the effect of preserving moisture and heat and are beneficial to seedling germination and reduction of irrigation labor intensity; with addition of the probiotics beneficial to seedling growth, seedlings are endowed with certain disease resistant capability, have many root hairs at roots, good root climbing effect as well as thick and strong stems and are high in emergence rate and survival rate, fertilizer application and pesticide spraying are almost unnecessary in the seedling raising process, labor is reduced greatly, and the viable number of the prepared microecologically agricultural polyvinyl chloride plastic masterbatch and seedling growing tray is high.

Description

technical field [0001] The invention relates to the field of agricultural plastic masterbatch, in particular to a polyvinyl chloride micro-ecological agricultural plastic masterbatch containing probiotics and a seedling raising tray made thereof. Background technique [0002] The existing rice seedling raising technology mainly adopts the seedling tray to raise seedlings, and after the seedlings grow to a certain degree, the seedling tray is transplanted to the field. Seedling raising is an important process, and the seedlings grow well in the seedling raising process, which is conducive to the growth of the seedlings in the later stage. The seedling trays used in the seedling raising process also have a certain impact on the germination rate and growth status of the seedlings. Therefore, by improving the conditions of the seedling trays, the growth of the seedlings in the seedling raising process can be improved, and the germination rate of the seedlings can be increased. ...

AI Technical Summary

Problems solved by technology

[0003] At present, the seedling trays commonly used in agriculture have a short lifespan and can basically only be used once. When they are used for the second time, the quality will decline and cannot meet the requirements of seedling raising.

Commonly used seedling trays are only used to temporarily cultivate seedlings and cannot provide other nutrients for the growth of seedlings. Therefore, regular fertilization, spraying of insecticides and pesticides are required during the seedling raising process, which not only increases the labor force, but also affects the emergence rate and Survival rate and germination quality, etc.
