新葵杂7号施肥试验

Fertilizer Experiments of Xinkuiza No.7

为了良种良法配套,2009年在新疆农业科学院安宁渠进行了新葵杂7号施肥试验。结果表明:种肥以三料磷肥、磷酸二铵等氮、磷化肥为主,苗期、蕾期以尿素、磷酸二铵等氮素化肥为好,其籽实产量、产油量最高。施用氮、磷化肥能显著提高油葵单位面积籽实和油脂产量;在氮、磷配合施肥中相对增施磷肥油葵籽实增产显著,同时籽实皮壳率也相应提高,要取得高产、高油的目的一定要注意氮、磷的配合比例。

In order to find the optimum planting method in production,the fertilizer experiment of Xinkui No.7 was conducted in Anningqu experiment field of Xinjiang Academy of Agricultural Sciences in 2009.The result showed that it could obtain the highest seed yield and oil yield when seed fertilizer mainly with triple phosphate,diammonium phosphate and other N,P fertilizer,urea,diammonium,phosphate and other N fertilizer in seedling stage and bud stage.Application of N,P fertilizer could significantly increase seed and oil yield per unit area of sunflower;In N P fertilization with relative increasing of P fertilizer could significantly increase sunflower seed yield,and the seed hull ratio increase correspondingly;It should be pay more attention on the ratio of nitrogen and phosphorus fertilizer for getting the high yield and high oil.
