Abstract

The present invention relates to an anti-leakage water retaining agent for arid land and semiarid land. The anti-leakage water retaining agent is fine solid powder composed of clay, a calcium agent, an adhesive and nutrient components. When the soil is ploughed, the anti-leakage water retaining agent is directly spread into the soil, and the anti-leakage water retaining agent can form gel once encountering water; thus, the anti-leakage water retaining agent can present the downward infiltration of a large amount of water and has the function of fertilizer retention. The anti-seepage water retaining agent is convenient for mechanized operation.

Description

Arid, half-dried nonirrigated farmland seepage-preventing water-retaining agent
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) 2Or CaCl 2, Ca (HCO 3) 2, CaO etc.Tackiness agent is: water glass (Na 2SiO 3, 9H 2O) or cement, polyvinyl alcohol (PVA), polyacrylic acid (PAA), polyacrylamide (PAM), sodium alginate, Mierocrystalline cellulose, modified starch etc.Nutrient can be flyash or peat, humate, (NH 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.
[embodiment 1]
Experiment is the aeolian sandy soil that Inner Mongol Naiman Banner white tone tower draws bush with soil, belongs to fine sand, is the soil diameter of packing into 5cm, grows in 1 meter the Glass tubing, seepage flow COEFFICIENT K=3.30 * 10 during seepage-preventing water-retaining agent of no use -3Cm/s, this value belongs to the fine sand seepage flow.
Percentage ratio is 50% kaolin by weight, 10%CaCl 2, 10% sodium alginate, the seepage-preventing water-retaining agent that 30% flyash is made is got a gram and is put among the fine sand of above-mentioned Glass tubing, surveys its seepage flow COEFFICIENT K=4.27 * 10 -4Cm/s (cel), this value belongs to the loess seepage flow.
[embodiment 2]
Condition is with embodiment 1, and seepage-preventing water-retaining agent consists of 60% hydromica clay, 10%Ca (H 2PO 4) 2, 10%PAA, 20% peat.Survey K=2.0 * 10 -4Cm/s, this value belongs to the light loam seepage flow.
[embodiment 3]
Press the condition of embodiment 1, seepage-preventing water-retaining agent consists of 50% montmorillonite clay, 10%CaO, 10%Na 2SiO 39H 2O, 30% humic acids iron is surveyed K=6.14 * 10 -5Cm/s, this value belongs to the mild clay seepage flow.
[embodiment 4]
Press the condition of embodiment 1, seepage-preventing water-retaining agent consists of 50% montmorillonite clay and water removes female clay half and half composite soil, 10%Ca (HCO 3) 2, 5%PAM, 10% urea, 10%KH 2PO 4, 5% cement, 10% peat.Survey its K=2.30 * 10 -5Cm/s, this value belongs to the mild clay seepage flow.
