Description
Technical Field
The invention belongs to the technical field of soil improvement, and particularly relates to a compound fertilizer for improving moderate saline-alkali soil and secondary saline-alkali soil.
Background
Saline-alkali soil is soil in which soluble salt or substituted sodium ions in the soil are difficult to grow after the concentration reaches a certain degree. The saline soil, alkaline earth and alkaline soil can be divided into two categories. All occur in arid regions where the evaporation capacity is greater than the precipitation capacity and have geochemical conditions for salt and alkali accumulation. The secondary salinized soil is unsalted soil or original light salinized soil, and is changed into heavy salinized soil due to the action of excessive chemical fertilizers and the like and is abandoned. Because the mechanisms of salt and base damage to crops differ, there is also a difference in improvement.
In northwest China, particularly Gansu province, almost no land is neutral soil, the pH value of the culturable soil is generally between 8 and 8.5, and some soil is even between 8.5 and 9.0, so that a simple, economic and feasible method is urgently needed for soil improvement.
The improvement of saline-alkali soil is a worldwide problem and generally varies from place to place. The method comprises a biological improvement method, namely planting saline-alkali tolerant crops, wherein the alkali-tolerant crops also have the alkali-tolerant limit of growth, and the crops which are slightly suitable for growth are planted in the medium saline-alkali soil in the northwest region; the physical improvement method is to increase the water permeability of the lower soil and wash the saline-alkali soil by water by changing the geological structure, but the method needs to invest a large amount of water resources and has low practicability in northwest arid areas; the chemical improvement method is characterized in that inorganic acid raw materials or fertilizers are used for neutralizing saline alkali, the PH value of soil can be returned, the improvement cost is high, moderate saline alkali soil and secondary saline alkali soil are formed for a long time, the soil fertility is extremely low, only the PH value is changed, or the soil cannot be thoroughly improved into cultivated land, the investment is large in actual agricultural production, the return is slow, and the limitation is obvious.
Based on the fact that the traditional soil improvement method is not suitable for being popularized and used in improvement of large-area medium saline-alkali soil and secondary saline-alkali soil in northwest, the technical personnel in the field develop the compound fertilizer for improving the medium saline-alkali soil and the secondary saline-alkali soil.
Disclosure of Invention
The invention aims to provide a compound fertilizer for improving medium saline-alkali soil and secondary saline-alkali soil, and aims to solve the problems of high cost investment and incomplete effect of the traditional method in the improvement of large-area medium saline-alkali soil and secondary saline-alkali soil in northwest.
In order to solve the problems, the technical scheme of the invention is as follows:
a moderate saline-alkali soil and secondary saline-alkali soil improvement compound fertilizer is characterized in that: the raw materials comprise: 25-35 parts of organic acid, 8-12 parts of alkyl benzene sulfonic acid, 18-25 parts of attapulgite and 75-90 parts of bio-organic fertilizer.
Further, the organic acid is polymaleic acid.
Further, 30 parts by weight of polymaleic acid, 10 parts by weight of alkyl benzene sulfonic acid, 20 parts by weight of attapulgite and 80 parts by weight of bio-organic fertilizer.
Furthermore, the biological organic fertilizer contains 60 percent of organic matters, the number of effective viable bacteria is more than or equal to 2 hundred million/g, the total nutrient of nitrogen, phosphorus and potassium is more than or equal to 6 percent, and the trace elements in a chelated state are more than or equal to 2 percent.
The invention has the following beneficial effects:
(1) according to the invention, the characteristic that organic acid can neutralize alkali in soil is utilized, the pH value is reduced, the solubility of calcium sulfate and calcium carbonate in soil is improved, and calcium ions are used for replacing sodium ions absorbed by soil colloid; the excellent emulsifying, foaming, permeating, decontaminating and dispersing performances of the sodium alkyl benzene sulfonate are utilized to decompose salt and reduce salt damage; the unique dispersivity of the attapulgite is used for resisting salt and alkali, has colloid constitution and higher adsorption capacity, can adsorb heavy metal ions in soil, supplements trace elements, rod-needle-shaped structures and anion and cation effects in the soil, can improve the soil and loosen the soil, and eliminates hardening. The biological organic fertilizer is used as a carrier of organic acid and sodium alkyl benzene sulfonate, so that the saline and alkaline can be reduced, the soil poor due to the saline and alkaline can be quickly and timely supplemented, and nutrients required by crops can be provided as soon as possible; the application is more convenient.
(2) According to the invention, the specific ratio of the polymaleic acid and the alkylbenzene sulfonic acid is adopted, the optimal effect of reducing the salt alkalinity is realized, the synergistic effect is exerted with the active ingredients such as the attapulgite and the bio-organic fertilizer, the salt alkalinity of the soil is reduced, the soil storage capacity is high, and the nutrient regulating capacity is high, so that the salt alkalinity problem is solved fundamentally.
(3) The invention can be used in various barren saline-alkali soil to be improved, can be cultivated in an improvement period once being applied, can also be used in the growth process of planting crops in the saline-alkali soil, improves the crop yield on the premise of not damaging the growth period and the growth rule of the crops, and simultaneously desalts and alkalifies the soil, thereby preventing the adverse effect and the yield reduction of the crop growth caused by the application of the medicament in the chemical improvement.
(4) The invention has simple formula and low cost, is very suitable for being popularized and used in the improvement of large-area moderate salinized soil and secondary salinized soil in northwest, and has prominent effects in various aspects such as economic benefit brought by yield increase, environmental benefit, ecological benefit, social benefit and the like brought by soil improvement.
