Abstract
A water-preserving agent for preventing water permeation in dry or semi-dry farmland is a fine solid powder prepared from clay, calcium preparation binder and nutrients. It can be directly spread into soil when the soil of said farmland is turned up, and can become gel when it is in contact with water, so preventing permeation of water and perserving fertilizer.
Description
The present invention is the seepage-preventing water-retaining agent in a kind of arid, half-dried nonirrigated farmland.
Rainfall amount is few in the arid and semi-arid lands, evaporated quantity of water is big, and rainwater and irrigation water ooze under a large amount of, influences the normal development of crop.Patent CN-1201062A and CN99101967.9 utilize water miscible liquid to form water-retaining film on the stratum, in the implementation process all water be modulated into the film emulsion.But surface water often discomfort is fit to do irrigation water, and many broken countrys generally need be got underground water from the 70-100 rice degree of depth, and are very inconvenient, and this patent works out the seepage-preventing water-retaining agent that a kind of dry method is used at these situations.It can be used for all areas that are unfavorable for the water operation, and helps mechanized.
Seepage-preventing water-retaining agent of the present invention is to be main raw material with the clay, adds the solid fines that additive mixes in right amount.Directly remove in the soil when ploughing, just can form gel in case meeting moisture content, what both prevented big water gaging oozes and plays function of fertilizer retention down.
Clay used in the present invention can be selected from kaolin clay, montmorillonite clay, hydromica clay and mixed clay thereof.Additive is by the calcium agent, and tackiness agent and nutrient are formed.The calcium agent is: Ca (H
2PO

4)
2HPO
4, KH
2PO
4, urea etc.In additive, can add sterilant as required.Clay, the calcium agent, the weight percentage of tackiness agent and nutrient is respectively: 40-60%, 5-15%, 5-15% and 30-50%.With above-mentioned composition press the certain weight ratio mechanically mixing, pulverize seepage-preventing water-retaining agent.
