摘要
通过在膜下滴灌水稻苗期分2次随水滴施腐植酸钾,研究腐植酸钾对膜下滴灌水稻生育期和产量的影响。结果表明,增施腐植酸钾的膜下滴灌水稻比对照提前5 d成熟,苗期水稻根长增加1.09 cm、根质量增加0.03 g,水稻成熟后株高增加2 cm,实收产量增加51.9 kg/667 m^2。故在膜下滴灌水稻出苗水、头水分别增施0.5、1.0 kg/667 m^2腐植酸钾,可缩短膜下滴灌水稻生育期并提高产量。
The current research investigated the effects of potassium humate on the growth period and yield of rice under film-mulched drip irrigation conditions.Potassium humate was applied to rice plants with water drops twice at the seedling stage of rice under drip irrigation conditions.As a result,the rice plants applied with potassium humate under drip irrigation conditions ripened five days earlier than the control;at the seedling stage,the root length of rice plants increased by 1.09 cm and the root mass increased by 0.03 g;at the mature stage,the plant height rose by 2 cm;and the actual yield rose by 51.9 kg/667 m^2.In conclusion,adding 0.5,1.0 kg/667 m^2 potassium humate to rice seedling water and first irrigation water respectively could shorten the growth period of rice plants cultivated under film-mulched drip irrigation conditions and increase the yield.
