近年来,红壤低产田扩种绿肥,特别是红花草,在生产和科学实践上,引起了广泛的重视.本省丘陵地区田多、劳力少,若单靠搬运大量农家肥料来改良低产田,不论从肥源和劳力的特点来看,都是不现实的.实践证明,扩种红花草绿肥是红壤低产田地区就地取材、广辟肥源、迅速提高地力和产量的根本途径.群众反映:“红花长一寸,抵得一层粪”;“铲铲担担,不如绿肥一篮”,它说明了红花草在改造低产田中的重要地位.现就几年来本地种植红花草的经验和试验研究资料,进行分析讨论,以供红壤低产田地区推广红花草参考.一、红花草对提高红壤性低产田水稻产量的重大作用红花草作为本田绿肥翻沤后,能供给大量氮、磷、钾养分,对提高低产田水稻产量非常显著,特别是板沙田和死黄泥田,增产效果更为突出.根据178斤调查和试验资料,每100斤红花草在低产田可以增收早稻谷
In recent years, the expansion of red soil low-yield fields green manure, especially red flowers, in production and scientific practice, has attracted widespread attention.Farmland hilly areas, less labor, if only by moving a large number of farm manure to improve low-yield fields, regardless of, From the characteristics of man-made fertility and labor point of view, are unrealistic.Experience has proved that the expansion of red flowers and green manure is a red soil low-yield fields in the local access, broaden sources of fertilizer, rapid increase in productivity and yield the fundamental way.The masses reflect: “The safflower is one inch in length and worth a ton of shit,” and “shovel shovel is not as good as a green manure basket.” It illustrates the important role of safflower grass in transforming low-yielding fields. Data for analysis and discussion for the promotion of red flowers in low-yield red soil area reference I. First, the red flowers to improve the yield of red soil low-yielding major role in the production of red flowers Honda Green Fertilizer turned over, can provide a large number of nutrients nitrogen, phosphorus and potassium , To improve the yield of low-yielding rice is very significant, especially in Pak Sha Tin and dead yellow paddy field, yield more prominent.According to 178 kg of survey and test data, per 100 kg of safflower grass in low-yield fields can be increased early rice
