影响我省旱地小麦发展的主要因素是干旱和地瘦,而旱与瘦互有联系,改善士壤营养条件就可以提高士壤水分的有效利用率,增强作物的抗旱性能。过去我们在这方面作了一些研究工作,总结出瘦红壤地麦增产的五项措施,发挥了“士壤水库蓄水”的作用。为了进一步解决影响我省地麦发展的限制因子—干旱,我组于1982—1983年进行了地麦种植行向与士壤水分关系的研究。试验的初步结果说明:地麦迎风(与风向垂直)开沟种植比顺风向开沟种植有利于保持士壤水分,提高地麦产量。
The main factors influencing the development of dryland wheat in our province are drought and lean, and the relationship between drought and leanness. Improving the nutrient conditions of lettuce can improve the effective utilization of soil moisture and enhance the drought resistance of crops. In the past, we made some research work in this area, summed up five measures to increase wheat production in thin red soil and played a role in “reservoiring Shihe reservoir.” In order to further solve the limiting factor affecting wheat development in our province - drought, our group conducted a study on the relationship between wheat planting and soil moisture in 1982-1983. The preliminary results of the experiment showed that wheat dominance in the wind (vertical to the wind direction) was better than ditching in the open wind to maintain the soil moisture and increase the wheat yield.
