Abstract
This invention discloses an anti-seeping agent used in water soils. The anti-seeping agent comprises: polyacrylamide 75-85 parts, bentonite 5-10 parts, calcium peroxide 15-50 parts, and potassium dihydrogen phosphate (or amino acid powder) 10-20 parts. The anti-seeping agent can effectively prevent water seeping and fertilizer loss when used in water soils. In draught, the anti-seeping agent can retain water and protect crops. Besides, the anti-seeping agent can also loosen and activate soils, and thus accelerate the growth of crops.
Description
Technical field
The present invention relates to the farmland water-saving field.
Background technology
After using in a large number for many years based on the agricultural chemicals of chemical fertilizer, part aquatic crops farmland (mainly being rice terrace) soil compaction is serious, moisture underground leakage amount is very big, cause peasant's water of productive use cost and man-hour to increase, simultaneously because of the dehydration of underwater cultivation layer, cause fertilizer nutrient to run off, cause the tardy underproduction of crop.The leakage of some sands own is big in addition, and it is big because of leakage to do the paddy field with sand, and water requirement is bigger, and fertilizer nutrient runs off even more serious.At present, also do not prevent the effective measure of dehydration of underwater cultivation layer and control underground leakage both at home and abroad.
Technology contents
Purpose of the present invention mainly is to provide a kind of permeability-reducing admixture for paddy field at the deficiency of the effective measure that also do not prevent dehydration of underwater cultivation layer and control underground leakage at present both at home and abroad, and it is made up of polyacrylamide and calcium peroxide; Its weight part proportioning is:
Polyacrylamide 75-85 calcium peroxide 15-50 wilkinite 5-10.
It also has potassium primary phosphate, and its weight part proportioning is:
Polyacrylamide 75-85 wilkinite 5-10
Calcium peroxide 15-50 potassium primary phosphate 10-20.
Potassium primary phosphate available amino end acid pulvis substitutes.
It also has zinc sulfate, and its weight part proportioning is:
Polyacrylamide 75-85 calcium peroxide 15-50 wilkinite 5-10
Potassium primary phosphate 10-20 zinc sulfate 10-20.
Advantage of the present invention is: 1, the present invention be used for the paddy field can prevent effectively the dehydration of underwater cultivation layer and control underground leakage; 2, can significantly reduce the underground leakage water yield, reduce fertilizer nutrient and run off, conserve water with fertile cost and man-hour; 3, when drought and water shortage, can play and slow down damage caused by a drought, reach the effect that water conservation is kept a full stand of seedings; 4, loose activating soil promotes crop growth, reaches the effect of water-saving and yield-increasing.
Embodiment
Embodiment 1: get 80 kilograms of polyacrylamides, 7 kilograms of wilkinites and 25 kilograms of mixing packs of calcium peroxide and be finished product.
Embodiment 2: get 75 kilograms of polyacrylamides, 8 kilograms of wilkinites, 20 kilograms of calcium peroxides and 15 kilograms of mixing packs of potassium primary phosphate and be finished product.
Embodiment 3: get 75 kilograms of polyacrylamides, 7 kilograms of wilkinites, 20 kilograms of calcium peroxides, 15 kilograms of potassium primary phosphates and 15 kilograms of mixing packs of zinc sulfate and be finished product.
Using method: rice seedling was transplanted to the front and back, paddy field in 1-2 days, behind 0.5 kilogram of per 1 mu of usefulness permeability-reducing admixture for paddy field of the present invention and the dried fine sand mixing of 7.5-10 kilogram, spread fertilizer over the fields in the paddy field equably.
Principle of work: utilize polyacrylamide and wilkinite dispersion, the throwing out in soil, change soil physical chemistry character, form new crumb structure, stop up the following capillary channel of underwater cultivation layer.Calcium peroxide can decomposite the oxygen that helps plant growth in soil.Potassium primary phosphate and zinc sulfate provide necessary trace element for plant growth.This product is tried out through 1000 mu of serious rice fields of seepage, and the antiseep effect is fairly obvious.Compared with the control, 1 cun dark water is irritated in the contrast field, only can keep about 1 day, and the field face be cannot see open fire.Can keep 10-15 days after using this product, the field face is still seen open fire, does not influence plant growth.
