新疆南疆地区沙地燕麦间作对紫花苜蓿当年建植效果的影响
Effects of Oat Intercropping on Alfalfa Establishment in Sandy Land of Southern Xinjiang in the Sowing Year
摘要
Abstract
[Objective]The study was conducted to clarify the effects of oat intercropping on the establishment and first-year yield of alfalfa in sandy land in Luopu County,southern Xinjiang,and to provide a technical basis for efficient alfalfa establishment in sandy areas.[Methods]The single factor design was used in the experiment,and two treatments were set up,including 1∶1 row intercropping of oat and alfalfa,and alfalfa monoculture.The emergence rate,seedling preservation rate,seedling growth rate and yield of alfalfa were measured.Independent sample t test was used to analyze the differences between treatments.[Results]The emergence rate of alfalfa in intercropping treatment was(88.0%±4.2%),which was 60.0%higher than that in monoculture treatment(55.0%±5.7%),and the difference was extremely significant(P<0.01).The average daily growth of alfalfa seedlings in intercropping treatment was 0.13 cm,which was 44.4%higher than that in monoculture(0.09 cm),and the branching stage was 3 to 5 days earlier.The fresh grass yield of alfalfa in the first crop of intercropping treatment was 13 789.5±3 340.5 kg/hm2,which was 112.2%higher than that of monoculture(6 499.5±1 300.5 kg/hm2,P<0.01).The total fresh grass yield of two crops in the whole year was 21 789.0 kg/hm2,and the hay yield was 5 925.0 kg/hm2.[Conclusion]The oat-alfalfa intercropping in a 1∶1 row ratio in the sandy land of southern Xinjiang,combined with the application of organic fertilizer and micro-sprinkling irrigation at seedling stage,can significantly improve the establishment performance of alfalfa in the sowing year,realize both establishment and harvest in the sowing year.This approach would alleviate the difficulties of alfalfa establishment in sandy areas of southern Xinjiang and had potential for extension and application.关键词
