Degradation type multifunctional substrate for planting and preparation method thereof

Abstract

The invention discloses a degradation type multifunctional substrate for planting and a preparation method thereof. The degradation type multifunctional substrate is mainly prepared from raw materials in parts by weight as follows: 20-60 parts of crop straw, 20-60 parts of bentonite, 10-30 parts of attapulgite, 0.1-3 parts of polyacrylamide and 1-3 parts of pregelatinized starch, wherein the crop straw is crushed and fermented before being used. The substrate for planting has good water absorption capacity, water retentivity and water releasing property, can improve desertified land and enhance the drought resistance of crops and contain a large quantity of microelements suitable for plant growth; the wall of the substrate for planting has moderate strength and shelling is not required after seedling raising; the substrate cannot damage roots or seedlings, is convenient to transport, facilitates integrated planting, can be naturally degraded in soil, causes no pollution to the soil, has a certain fertility improvement function, is beneficial to plants and the soil, contributes to improvement of natural environment and promotes ecological development.

Description

technical field [0001] The invention relates to the fields of planting in sandy soil and arid areas, fertilizer technology, agricultural waste recycling, etc., and specifically relates to a degradable multifunctional planting treasure prepared by using bentonite, straw, etc. as main raw materials and a preparation method thereof. Background technique [0002] As we all know, global water shortage, drought, and desertification are seriously threatening the living environment of human beings. According to relevant reports, 2,100 square kilometers of desertified land is added every year in my country due to drought, and more than 80% of the cultivated land is affected by drought and other reasons, which affect the growth of crops. At present, my country's desertified land is increasing day by day, and there are a large number of barren mountains and bald mountains in some areas. The vegetation of the barren hills in the Gobi is urgent. [0003] With the loss of humus and organ...

Problems solved by technology

However, the biggest shortcoming of the degradable paper nutrition bowl is that its degradation time cannot meet the requirements of various seedlings for seedling raising time, so the degradable paper nutrition bowl has not been widely used

[0007] Chinese patent (Application No. 991135547) discloses "Plant Fiber Seedling Pot and Its Manufacturing Method", which adopts plant fiber material, adds starch as a binder, uses paraffin or rapeseed oil as a release agent, and molds it under heating conditions. This method needs to use a large amount of starch and rapeseed oil in the production process, and its production cost and price are very expensive. If paraffin is used instead of rapeseed oil, although the cost can be slightly reduced, paraffin is not easy to decompose in the soil. Soil structure, so not suitable for large quantities

The seedling pot has good water storage performance, moderate pot wall strength, no shelling after seedling raising, no damage to roots or seedlings, convenient for pot seedling transportation and integrated planting, can be naturally decomposed in the soil, and has no pollution to the soil. And it has a certain fertilizing effect; but the above-mentioned seedling pots are not strong in absorbing water and retaining water, so they are not suitable for planting plants in deserts.
