管道输液滴干对核桃生长、果实的影响
Effects of pipeline trunk transfusion and drip on walnut growth and fruit
摘要
Abstract
We studied the integrated management of water and fertilizer pesticide on walnut cv. Liaohe with pipeline trunk transfusion and drip irrigation technology, in order to achieve the goal of water conservation, efficient use of fertil-izers and pesticides, get better yields and improve quality so as to explore a new way for the quality and efficiency of walnut. We Compared with the soil fertilization treatment and conventional management,and Determined the leaf SPAD, leaf area, new shoots length, new shoots diameter, soil water content, yield per plant, single fruit weight, kernel rate, black fruit rate, and so on. The result showed that compared with soil fertilization treatment and conventional manage-ment, the pipeline trunk transfusion and drip irrigation treatment increased the leaf SPAD value by 20.39% and 75. 27%, leaf area increased by 18.27% and 51.54%, new shoots length increased by 7.03% and 13.73%,new shoots diam-eter increased by 21.92% and 27.14%, trunk girth increased by 20.52% and 24.28%, soil water content of 0-20 cm soil layer increased by 8.63% and 8.52%, yield per plant increased by 21.62% and 73.08%, single fruit weight increased by 14.55% and 23.53%, the kernel rate increased by 11.40% and 12.44%,the black fruit rate decreased by 88.97% and 91.74%, respectively. It showed that pipeline trunk transfusion and drip irrigation technology could greatly promote the growth of tree, improve the yield of walnut and walnut fruit quality. This mode could strengthen the resistance ability of walnut, reduce the black fruit rate, and achieve the goal of high yield and stable yield of walnut. This experiment pro-vides a sufficient basis for popularization and application of pipeline trunk transfusion and drip irrigation technology.关键词
