红豆草生长期需水规律的研究

通过以不同水量在相同时期内和相同水量在不同时期内供给栽培红豆草在生长期内试验,获得了牧草种子产量和饲草产量差异显著的结果证明,在生长期内红豆草立地土壤水分的适宜供给量及最佳供给时期是种子和饲草获得高产的两项重要因素。

Studies on Water—Requirement in Growing-up Period of Onobrychis Viciaefolia

Two water-supplying experiments were conducted in this study. In experiment Ⅰ, the water was supplied in same amount at different periods, while in experiment Ⅱ, the water was supplied in different amount at the same periods. Differences in yields of seeds and forage between the two experi ments were observed. It was found that the appropriate amount and the right moment of water supply might be two important factors for Onobrychis viciaefolia in growing-up period in order to Obtain a good yield of seeds and forage.
