在大面积高产优质栽培中,根据麻黄的生育特性和对比试验,667平方米育壮苗35万株,麻黄鲜草产量可超吨。现将麻黄优质高产栽培技术介绍如下。 一、育苗 麻黄在苗床中大约生长300～360天,最佳播期为5月上旬(土温稳定在15℃～16℃)。由于麻黄种子小,顶上能力弱,播种宜浅不宜深,苗期必须及时补水、除草,做到种子落地管理跟上。根据一级种子发芽率60％、千粒重8
In a large area of high yield and quality cultivation, according to the reproductive characteristics of Ephedra and comparative tests, 667 square meters nurturing seedlings 350 000, Ephedra fresh grass yield can exceed tons. Ephedra now high-quality high-yield cultivation techniques are as follows. First, nursery ephedra growth in seedbed about 300 to 360 days, the best sowing date early in May (soil temperature stabilized at 15 ℃ ~ 16 ℃). Due to the small ephedra, the ability of the top of the weak, shallow sowing should not be deep, seedling must be timely replenishment, weeding, seed management to keep up. According to a seed germination rate of 60%, 1000 grain weight 8
