Compound improving agent for planting of allium polyrhizum in saline land and improving method thereof

Abstract

The invention relates to the technical field of improvement of saline land, and discloses a formula of a compound improving agent for planting of allium polyrhizum in saline land. The formula consists of the following raw materials in parts by weight: 30 parts of humic acid, 150 parts of desulfurizing gypsum, 18 parts of residue of furfural, 12 parts of ferrous sulfate, 25 parts of calcium superphosphate, 110 parts of ammonium sulfate, 10 parts of calcium nitrate, 50 parts of urea, 65 parts of plant ash, and 20 parts of fly ash. The formula has the advantages that the soil environment of saline land is effectively improved, the salt content of saline land is greatly reduced, the PH (potential of hydrogen) value in soil is reduced, the content of nutrient matter required in the planting process of alkali scallion is greatly increased, the cost of used raw materials is low, the preparation is convenient, the survival rate of allium polyrhizum in saline land is greatly increased, and the diet condition of local residents is improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a compound improver for planting alkali onion in saline-alkali land and an improvement method thereof. Background technique [0002] Saline-alkali land refers to the salt contained in the soil that affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which 99.13 million hectares are in my country. The formation of alkaline soil and alkaline soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. Mild saline-alkali soil refers to its emergence rate in 70%-80%, its salt content is less than 3 / 1,000; heavy saline-alkali land refers to its salt content exceeding 6 / 1,000, and the emergence rate is lower than 5...

Problems solved by technology

[0003] Suaeda salsa, also known as yellow mustard, is the seedling of Suaeda salsa, an annual herb of Chenopodiaceae. Because it mostly grows in saline-alkaline areas, it is an important food for people in saline-alkaline areas. It has high nutritional value and contains a variety of minerals. The human body needs, in addition, it is also rich in dietary fiber, which can stimulate gastrointestinal peristalsis, help digestion, and prevent rectal cancer, diabetes, gallstones, hemorrhoids and other diseases, but the production of alkali onion needs to be within a certain pH range, and our country has A large number of severe saline-alkali land and moderate saline-alkali land are not completely suitable for the growth of Alkali onion, thus limiting the output of Alkali onion. If the local saline-alkali soil environment can be improved and its pH value can be reduced so that it can be suitable for the cultivation of Alkali onion, it can give The food environment of the local people has been greatly improved. For this reason, we provide a compound improver for planting alkali onion in saline-alkali land, its improvement method and its preparation process
