桑苗生产以前多采用嫁接法,成苗需2年时间,也很难保留新品种的特性。下面介绍一种1年可成苗的乙烯树脂棚房扦插育苗法。其育苗期短,扦插后40—50日就能成苗。且不易受气象条件影响。乙烯树脂棚房的大小可根据所预定的苗数而定。在宽4.6米、高2.2米、长10.0米的规模下可扦插4,000株左右。如图1所示。扦插盆的放置面约向下挖10厘米,地面全部用乙烯树脂薄膜覆盖,以提高保温效果。将扦插盆并列于上面(9×8厘米),再用薄膜做成隧道状,晚上在它上面还要
Sangmiao production before the use of grafting, seedlings take 2 years, it is difficult to retain the characteristics of new varieties. The following describes a 1 year seedlings of vinyl shelter cuttage nursery method. The nursery period is short, 40-50 days after cutting can become a seedling. And not easily affected by weather conditions. Vinyl shed size can be based on the number of seedlings scheduled. In the width of 4.6 meters, 2.2 meters high, 10.0 meters long scale cuttings around 4,000. As shown in Figure 1. Cuttings pots placed about 10 cm down to dig the ground covered with vinyl film, in order to improve the insulation effect. The cutting pots and juxtaposed above (9 × 8 cm), and then made of tunnel-like film, even at night above it
