保留分蘖不间苗对高密度种植饲用型甜高粱土壤含水量及产量的影响

Tiller Break or Keep Type on High-density Planting Forage Sorghum the Influence of Soil Moisture Content and Yield

为了研究饲用型甜高粱掰除分蘖和保留分蘖以及是否间苗同产量的关系,通过采用大田对比随机区组的方法,研究土壤含水量、植株外部形态及产量。结果表明:保留分蘖、不间苗处理能高效利用降水和灌水,使植株显著增高,单株总茎数增加,显著增加产量,较掰除分蘖、间苗处理增产12.87%。高密度种植饲用型甜高粱保留分蘖不间苗不仅能显著增加产量,同时还可以减少掰除分蘖和间苗定苗造成的人力财力损失。

In order to study in addition to forage sorghum breaking tiller and tiller retention and whether thinning relationship with the production, by using the method Ota randomized comparison group, the study of soil moisture, plant morphological and yield. The results showed that： keep the tiller, not thinning treatment could efficiently utilized rainfall and irrigation, the plants increased significantly, increasing the total number of stems per plant, significantly increased yield, in addition to breaking than the tiller handle thinning yield 12.87%. High-density planting forage sorghum reserved tiller not thinning not only significantly increased production, but also could reduced the loss of human and financial resources in addition to the tiller and breaking thinning caused.
