Saline-alkali land improving and fertilizing agent and preparation method thereof

Abstract

The invention discloses a saline-alkali land improving and fertilizing agent and a preparation method thereof. The saline-alkali land improving and fertilizing agent are mainly prepared from 20 to 40 portions of fly ash, 10 to 20 portions of humic acid and 5 to 10 portions of organic substance through processes of crushing, matching and mixing, granulating, drying, cooling, sieving, magnetizing and the like. Compared with the prior art, a product of the invention has the advantages of short period for improving the saline-alkali land, high efficiency and low cost; if 50 kilograms of product is applied to each acre as base fertilizer, the seedling emergence rate of planted crops can reach 98 percent, for example, 406 kilograms of wheat is harvested in each acre and is equal to the planting harvest of the normal soil, and after the harvest, the salt content of the soil is 0.55 percent and the desalination rate reaches 47 percent through soil measurement, so that the soil granule structure is improved; and the product can reduce the salt and restrain the alkali, is soil improvement agent, also can be used as fertilizer, reduces the planting cost, has the same using method as a common fertilizer when the product is used as the fertilizer, has remarkable fertilizer efficiency in saline-alkali and poor soil, and can increase the yield by 10 to 30 percent relative to different crops compared with the used common fertilizer. Therefore, the saline-alkali land improving and fertilizing agent not only can improve the soil granule structure, but also can accelerate the improvement of soil desalination; meanwhile, the saline-alkali land improving and fertilizing agent is fertilizer, greatly reduces the planting cost of peasants, and improves the planting income of the peasants.

Description

Technical field:

[0001] The invention relates to a saline-alkali soil improvement fertilizer and a preparation method thereof. Background technique:

[0002] The improvement of saline-alkali land has always been a worldwide problem, and many countries are committed to the control and utilization of saline-alkali land. At present, there are many ways to improve and control saline-alkali land, such as biological improvement by planting pioneer crops such as rice and alfalfa, physical improvement by washing salt with water, and chemical improvement by using gypsum and sulfur. However, these improvement methods have the disadvantages of long improvement cycle, large investment and large water consumption. my country has more than 1.487 billion mu of saline-alkali land and low-yield fields affected by saline-alkali, many of which can be reasonably developed and utilized. Today, when cultivated land is being reduced by urbanization, desertification, desertification, and saliniza...
