种草木樨时施少量氮、磷肥可提高产草量,早已为大量的研究所证实,但在当前新疆的农业生产中尚少见。为此我们选用本区常用的麦田套种草木樨,通过麦田施肥来解决草木樨对磷营养之需,达到以磷增氮,以提高产草量,促进畜牧业发展之目的。在灰漠土,肥力中上等,其中有机质为1.68%、全氮为0.1%、全磷(以P_2O_3计)0.176%、磷解氮13.15毫克/100克土、速效磷3.97毫克/100克土的P_2O_3前茬小麦。1、施磷方式对小麦经济性状的影响
Planting a small amount of vegetation when the nitrogen fertilizer, phosphorus can increase the amount of grass, has long been confirmed by a large number of studies, but in the current agricultural production in Xinjiang is still rare. To this end, we use the common wheat field intercropping grass and mulberry in this area, and fertilize the wheat field to solve the need of phosphorus nutrition and achieve the purpose of increasing phosphorus and increasing the production of grass and promoting the development of animal husbandry. In the gray desert soil, fertility is middle and upper, of which organic matter is 1.68%, total nitrogen is 0.1%, total phosphorus (calculated as P 2 O 3) 0.176%, phosphorus nitrogen 13.15 mg / 100 g soil, available phosphorus 3.97 mg / 100 g soil P_2O_3 crop before wheat. 1, the impact of phosphorus application on the economic traits of wheat
