宁夏引黄灌区春小麦大面积500公斤高产试验研究

THE RESEARCH AND STUDY ON HIGH-YIELDING SPRING WHEAT WITH THE OBJECT OF 500 KG PER MU IN THE LARGE AREA OF NINGXIA IRRIGATION REGION DRAWING WATER FROM THE YELLOW RIVER

在总结宁夏引黄灌区春小麦高产经验的基础上，选择具有代表性的国营连湖农场（灌淤土；肥沃型）和平吉堡农场（淡灰钙土；瘠薄型）为试点，进行多项试验研究和大面积示范。连湖农场1989～1993年连续五年全场6500余亩小麦平均亩产超500公斤，百余亩连片麦田亩产超600公斤；平吉堡农场小麦单产水平连年大幅度上升，由1989年的413公斤上升到1993年全场5843．2亩平均亩产496．2公斤。通过试验研究；总结出不同土壤类型，不同土壤肥力条件下大面积亩产超过500公斤的高产规律，形成了可代表我国西北灌溉春麦区特色的高产栽培理论体系。

These research and study were based on summing up high-yielding experiences ofspring wheat in Ningxia irrigation region drawing water from the Yellow River, took therepresentative state farm of Lianhu and Pinjipu as the testing ground, conducted a number ofexperiments, research and setting an example in large area of wheat field. The average yield ofthe whole wheat field ab0ut 6500 mu on the state farm of Lianhu exceded 500 kg per mu for fiveyears in succession from 1989 to 1993, including the wheat field exceeding 600 kg per mu over ahundred mu. The level of average yield of wheat in the Pingiipu state farm increazed rapidlyyears in succession, going up from 413 kg per mu in 1989 to 496.2 kg per mu in 1993 in thewhole wheat field of 5843.2 mu. The high-yielding law exceeding the level of 50O kg mu in largearea under difference conditions of soil type and soil fertiliiy was put out, the theoretical systemof high yield cultivation representing farming peculiarity of Northwest China was taken shape.
