Problems solved by technology

The solid degradable mulch needs to consider its molding, transportation conditions and strength requirements during the laying process. Its thickness is generally much thicker than that of plastic mulch, and its price will be higher than that of plastic mulch. Most of them cannot be completely degraded, so its application subject to certain limitations

Embodiment Construction

[0008] First, dig three to four grams of lignite into an agate mortar with a medicine spoon, and grind it repeatedly until it becomes powdery. After about 15 minutes, until there are no large particles, then put the ground lignite on a 100-mesh sieve. Shake the sample sieve, take the lignite that has leaked through the sample sieve, weigh one to two grams accurately with an electronic balance, put it in a clean small beaker, add 30% nitric acid to oxidize, then stir with a magnetic stirrer for 30 minutes, and take off the small beaker , add sodium hydroxide solution to it to neutralize nitric acid, until neutral, transfer the lignite in the small beaker to a 500 ml flask.

[0009] Dissolve 15 g of crystalline sodium pyrophosphate and 7 g of sodium hydroxide in 1000 ml of water to prepare a sodium pyrophosphate alkali extract. Measure 150 ml of sodium pyrophosphate alkali extract, pour it into a 500 ml flask, and shake to mix to wet the sample. Cover the flask with a constant ...

Abstract

The invention discloses an environment-friendly humic acid mulching film. The humic acid mulching film comprises the following components in parts by mass: 40-90 parts of hydrochloric acid, 60-100 parts of nitric acid, 30-100 parts of sodium pyrophosphate, 40-90 parts of sodium hydroxide, 40-80 parts of cellulose glycolate, 30-100 parts of sodium lauryl sulfate, 30-80 parts of absolute ethyl alcohol, 40-90 parts of hexakis methoxymethyl melamine (HMMM), 40-90 parts of sodium silicate, 50-90 parts of glycerin and 100-120 parts of p-toluenesulfonic acid (TSA).

Description

technical field [0001] The invention belongs to an environment-friendly humic acid film and belongs to the technical field of light industry chemistry. Background technique [0002] From the available information, we can see that the deserts in the arid northwestern part of our country have a very large overall area, are widely distributed, and are increasingly endangered by desertification. More than 80% of the land in our country is suffering from unfavorable phenomena such as soil loss, drought, salinization, etc., and it is urgent to carry out different regulation and governance work according to local conditions. Soil loss, land desertification, soil salinization and soil environmental pollution have become very serious stumbling blocks to delay my country's economic and social development. [0003] Although our country is facing such a serious land problem, the method of using plastic film for crop planting has been widely adopted by farmers. The technology of using ...
