Study On Trace Irrigation Pipe Depths To Growth And Development Of Cucumber Cultivated In Sand、Pumpkin Cultivated In Matrix、Pepper Cultivated In Soil

Water scarcity and low agricultural water using efficiency are serious problems to hinder the development of agriculture in China. Trace irrigation technology can significantly improve agricultural water using efficiency. Cucumber cultivated in sand、pumpkin cultivated in matrix、pepper cultivated in soil as test materials, we analyze the effects of trace irrigation pipe depths on three different vegetable growth index, physiological indexes, yield, water use efficiency and so on, the test results showed that:1.In sand cultivation, trace pipe buried deeper, the greater the cucumber growth was inhibited after treatment Trace pipe depth of 5cm physiological parameters of cucumber, quality indicators were significantly improved compared to Sprinkler irrigation treatment, and trace amounts of irrigation Sprinkler irrigation treatment sand moisture content is low compared to a small change in amplitude. Trace pipe depth of 5cm handle relatively tiny spray water production efficiency improved 100.4%. So Trace pipe in sand culture cucumber cultivation optimum depth of 5cm.2.1n matrix cultivation, irrigation and CK treatment Trace Growth indifference Pumpkin. But the net photosynthetic rate, fruit quality Pumpkin leaves after trace amounts of irrigation treatments improved. Trace irrigation substrate moisture curve relative to Sprinkler irrigation treatment changes over time is relatively flat, trace tube depth of 6cm,12cm handle 667 m2 of relative water consumption decreased by Sprinkler irrigation treatment 65.7%,61.7%, trace Pipe Depth 6cm,12cm handle water production efficiency and Sprinkler irrigation treatment increased by 102% compared to 85.7%. So squash cultivation in the matrix of trace pipe optimum depth of 6cm.3.1n soil cultivation, the deeper the more beneficial to the growth of pepper, trace 20 cm depth processing (T4), chlorophyll content, water content and photosynthetic physiological indexes have greatly improved. Fruit quality and improve, especially the content of protein is significantly higher than other processing. Trace irrigation treatment overall under drip irrigation, soil moisture and the trace of irrigated soil moisture content under all over time more smoothly, trace irrigation treatment significantly below drip irrigation water, water production efficiency has improved greatly, the T4 drip irrigation water production efficiency of processing, processing respectively increased by 106.4%. Comprehensive pepper growth and physiological indicators, trace 20 cm depth, is conducive to the growth of pepper.
