Problems solved by technology

Desertified land, with the loss of humus and organic matter, gradually reduces the types and quantities of microorganisms in the soil, reduces biological activity, and gradually becomes lack of water retention and fertilizer retention, which is not conducive to the growth of plants. For the improvement of desertified land, the methods adopted include burying straws in a network and planting plants on the straws. This method has achieved certain results, but the improvement of water retention and fertilizer retention is not ideal; there are also pots filled with pots that are suitable for plant growth. Planting plants in poor soil, this method is not ideal for improving water retention, and the pots are made of non-degradable materials, such as cement, plastic, etc. These materials cause secondary pollution of the land

example 1

[0029] Example 1: A biodegradable bowl made of straw. The height of the bowl is 150mm, the diameter of the bowl mouth is 170mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl body, and a 50mm hole is made at the center of the bowl cover. Hole, fill 30 mesh zeolite in the height of one-third of the bowl body, fill the mixture of compost and local soil 1:2 on the zeolite, sow Caragana seeds to fill the nutrient bowl, and then water. The test results show that compared with the control (local desertification soil), the water content is increased by 13%, and the survival rate is increased by 12%.

example 2

[0030] Example 2: A degradable bowl made of degradable resin. The height of the bowl is 200mm, the diameter of the bowl mouth is 220mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl body, and a row of holes is made at the center of the bowl cover. 50mm hole, fill 20-mesh peat in one-third of the height of the pot body, fill the peat with a 1:4 mixture of compost and local soil, sow sandawang seeds to fill the nutrient pot, and then water. The test results show that compared with the control (local desertification soil), the water content is increased by 6%, and the survival rate is increased by 13%.

example 3

[0031] Example 3: A degradable bowl made of degradable resin. The height of the bowl is 150mm, the diameter of the mouth of the bowl is 170mm, a row of holes with a diameter of 3mm and an interval of 60mm are made at one-third of the height of the bowl body, and a row of holes is made at the center of the bowl cover. 50mm hole, fill 80-mesh vermiculite in one-third of the height of the pot body, fill the mixture of compost and local soil 1:6 on the vermiculite, sow Caragana seeds to fill the nutrient pot, and then water it. The test results show that compared with the control (local desertification soil), the water content is increased by 4.5%, and the survival rate is increased by 9%.

Abstract

A method for increasing the local water content and fertility of the desertized field by use of the degradable nutritive bowls in order to improve the desertized field includes such steps as preparing the degradable nutritive bowls consisting of perforated main body and cover, filling organic substance or minerals, filling the mixture of compost and soil, cultivating plant in the nutritive bowls, burying them in the desertized field, and irrigation.

Description

Technical field: [0001] The invention creates a method for improving local water retention and fertilizer retention of desertified land, a small environment suitable for plant growth, and restoring planting conditions of desertified land. Background technique: [0002] At present, the desertification of land in our country is increasing day by day. Protecting human's own homeland and speeding up the control of desertified land have become the frontier fields of scientific research. Desertified land, with the loss of humus and organic matter, gradually reduces the types and quantities of microorganisms in the soil, reduces biological activity, and gradually becomes lack of water retention and fertilizer retention, which is not conducive to the growth of plants. For the improvement of desertified land, the methods adopted include burying straws in a network and planting plants on the straws. This method has achieved certain results, but the improvement of water retention and ...
