Embodiment Construction

[0014] In the present invention, sodium hydroxide and ammonium hydroxide are added to the reaction of water, starch and acrylic acid, and the graft copolymer is obtained by reacting with ceric ammonium nitrate as an initiator at 50 DEG C. The process is: water → C 3 H 4 O 2 →NaOH→C 6 H 10 O 5 →NH 4 OH→Ce→separation→dry and pulverize→product, the weight percentage of each component is: C 3 H 4 O 2 32C 6 H 10 O 5 12

[0015] NH 4 OH 18 NaOH 10

[0016] Ce 0.8 Water 27.2

Abstract

The present invention relates to a water-absorbing moisture-holding soil humidity-regulating agent composed of acrylic acid, starch, ammonium hydroxide, sodium hydroxide, ammonium cerous nitrate (rare earth) and water through the processes of heating to 50-60 deg.C, mixing, separating, drying and pulverizing. Said invention can regulate dry and wet condition of soil, can make crops normally grow and can save water and save fertilizer.

Description

1. Technical field [0001] The present invention relates to a soil moisture conditioner. 2. Background technology [0002] At present, the agricultural production in some underdeveloped and arid regions of our country is still in the stage of relying on "sky" for food. When encountering natural disasters and droughts, crops will be greatly reduced in yield, or even grains will not be harvested. With the development and utilization of people and the continuous development of industrial production and agricultural production needs, the utilization of water resources is increasing, and my country is a water-deficient country, and the per capita water resources are only equivalent to 1 of the world's per capita / 4, ranking 12th among 153 countries in the world in terms of per capita water resources. By the middle of this century, my country will be close to the edge of water-stressed countries. Therefore, comprehensive and effective countermeasures and measures must be taken from...
