The Study On The Effect Of Catchment And Application In The Forestation With Automatic Irrigation Waterboxx In Xinjiang

In the green lawn, the spider mountain forest and small fort Woopen conditions.the water collection of automatic irrigation waterboxx shows a "Single peak curve", respectively.the annual quantity of water collection in box is 28.5L、31.2L、27.6L、The size of the order:retiremen>green lawn> Open area. The results showes that the automatic irrigation Waterboxx has the ability to collect rainwater, dew, snow, the water collection of automatic irrigation waterboxx shows a"Single peak curve" in different times, presents straight climb from 3 month.after 6 month.the maximum water collection of automatic irrigation waterboxx runs up to about 10L. With the increase of time, water collection shows straight down, until no longer change.Significant differences in content of time on Waterboxx(p<0.01). the differences of the site conditions on field surface temperature of Waterboxx lower part and box surface are not remarkable; the differences of Waterboxx on the box lower surface temperature and box outside surface temperature are significant(p＜0.01). But in June. July and August, the box lower surface temperature lower than the box outside surface temperature of 2 to 4℃. while in the other months. the box lower surface temperature higher than box outside surface temperature of 2 to 3℃, Show that the Waterboxx has the double functions of warming and cooling; From April to May, temperature of the lower surface of Waterboxx technology of forestation tree species higher than box outside surface of 1 to 2℃, Indicates that the Waterboxx has the effect of moisture preserving, temperature increasing.and it can promote the growth of root of tree species for afforestation.During June to August, temperature of the lower surface of Waterboxx technology of forestation tree species lower than box outside surface of 2 to 4℃,show that Waterboxx has the function of cooling, may be due to the occlusion from automatic irrigation waterboxx. and the reason of water has larger specific heat capacity, thereby reducing the soil temperature of summer plant.avoid afforestation tree species seedlings subjected to burning by high temperature in summer.On the conditions of waterboxx. the yield of water that Haloxylon ammodendron. Ulmus pumila and Acer negundo needed both presents rising with the increase of time. When added to a certain time.however, the yield of water decreased, This result is roughly same to the yield of water that plant growth needed The amount of water of Haloxylon ammodendron needed, growing in the one Waterboxx (49.85L). greater than Ulmus pumila and Acer negundo desired content(45.41L),this result may because of the rainfall of qitai county small than anningqu, whieling the evaporation greater than it.With the technology of waterboxx,there no obvious change of Haloxylon ammodendron water under 0-60cm soil layers (p>0.01),and there has large change of each layer of soil moisture under the control treatment (P< 0.01).The results show that Waterboxx has function of slowing down water desorption of the the micro environment in the mainland surface, creating a suitable environment for the normal growth of Haloxylon ammodendron.The period of tree leaf expansion with Waterboxx technology earlier than the control 2d or 3d,defoliation later than the control 4 d or 5d. which mainly due to Waterboxx can cause preservation of soil moisture and temperature increase; there was no significant difference between the survival rate of Ulmus pumila and Acer negundo with Waterboxx technology and those with flood irrigation (p>0.05).While the afforestation survival rate in the Haloxylon ammodendron test area of County with the Waterboxx technology is 21% higher than noirrigation afforestation;under the conndition of Waterboxx, respectively,the height growth and crown width of Haloxylon ammodendron is 10% and 30% higher than the control.The high growth of Ulmus pumila and Acer negundo under Waterboxx is 2.4% lower than the control. and the crown width is 43.4% higher than the control.Evaluating comprehensively to the result of Waterboxx-irrigation systems, irrigation, no irrigation 3 irrigation methods by using fuzzy comprehensive evaluation method,The results show that Groasis Waterboxx-irrigation system showed the best effect,it indicate that a high technology of Waterboxx is worthy of applicating and promoting.
