水肥耦合对库尔勒香梨生长、果实品质及产量的影响
Effects of water and fertilizer coupling on the growth,fruit quality and yield of Korla Fragrant Pear
摘要
Abstract
[Objective]To study the response of growth and fruit formation to water,nitrogen,phosphor-us and potassium of Korla fragrant pear in the hope of providing theoretical.[Methods]Basis for improving quality and increasing yield of Korla fragrant pear.Four factors of water,nitrogen,phosphorus and potassium were set in the test,among which,two levels of water were set.Nitrogen,phosphorus and potassium were set at three levels,namely water(2,400 kg/hm2;3,600 kg/hm2),nitrogen(150 kg/hm2;300 kg/hm2;450 kg/hm2),Phosphorus(1,12.5 kg/hm2;225 kg/hm2;337.5 kg/hm2),potassium(55 kg/hm2;110 kg/hm2;165 kg/hm2)to determine the growth,fruit quality and yield of pear trees.[Results](1)The growth amount of W1N2P3K1 branch was the highest,and the diameter of W2N3P2K1 branch was the largest.The range analysis of branch growth dynamics of Korla Fragrant Pear showed that W2N2P2K1 had the best effect on branch growth,and the results of branch diameter were consistent with the actual measurement.(2)It was seen that the growth trend of W1N2P3K,fruit shape was closest to the fitting growth curve,R2 was closest to 1,which was most consistent with the growth law.(3)W1N1P2K3 treatment ranked the highest,with the best fruit quality performance.(4)Its yield under W1N3P3K3 was the highest and the fruit weight of Korla fragrant pear was relatively good.[Conclusion]Considering pear tree growth,fruit quality and actual yield,the growth,fruit quality and yield of Korla Fragrant Pear treated with W1N3P3K3 are better.关键词
