Integrate Technologies Of The Anti-drought And Water Saving With Bio-chemicals For Fruit Trees In Beijing Suburb

Beijing is a city of water resource extremely in short supply, every department in the country has realized the importance and urgency of water-saving, much attention has paid to the construction of water-saving projects, and certain economic benefit, social benefit and environmental benefit have achieved. But because of the special conditions in some areas which are thin soil layers and quickly infiltration, potentiality of water-saving projects can't play insufficiently in some districts and it can't satisfy the water-saving demand, so it must cooperate with some non-engineering water-saving measure projects in order to improve water-saving potentiality. Through superabsorbent polymers, agent of anti-transpirant, etc. applied to fruit tree in suburb of Beijing, this paper reveals influence effect of the characteristic that water quality to soil absorbent polymers absorbs water in the land, integrating and optimization of biochemical integrated technology applied to water-saving culture in apple and grape in suburb of Beijing. The result shows: water quality has a certain degree of influence to water-absorbing characteristic, rate of water-absorbing reduces notably with increasing salt quantity and the trend of reducing become more and more gently, the water-absorbing time of same kinds of superabsorbent polymers in one price multiple cation is obviously higher than in two price, when it is in the range 6. 0-8.0 which is most suitable for crop-growing, pH value has in apparent influence on the water-absorbing characteristic; the most excellent schemes of agent of anti-transpirant, superabsorbent polymers and BGA for apple are 400 times of liquid, 300g / one, 2.5kg/one and for grape are 1.5g/m~2, 20g/one, 400g/one in suburb of Beijing.
