摘要
通过对河池市中低产田进行稻草还田试验研究,初步探索出在相同施肥与水分管理条件下,不同稻草还田量对水稻产量及农艺性状的影响。结果表明:不同稻草还田量,对水稻生育期没有影响,但能增加水稻分蘖数量,增加水稻产量。加大还田量,水稻产量也明显增加,稻农可按实际情况尽可能全量还田,以增加产量和收益。
After the experimental investigations on returning straw to field in medium and low-yielding land of He Chi, under the same condition of fertilization and water management,there are different effects of different quantity of returning straw to field on rice output and agronomic traits. The result shows that different quantity of returning straw to field can＇t affect the growth period duration of rice but increasing the number of rice tiller and output. According to the actual situation,the peasant can return the straw to field as much as possible for increasing the output and income.
