地膜平铺覆盖育秧,是当前最为经济有效的育秧方法,具有成本低、经济效果好的优点,而且成苗率高,秧苗生长矮壮、早发、早熟,具有高产秧苗的生理基础。但其效应的发挥,特别是减轻“贴膏药”,提高成苗率,则是地膜育秧技术中成败的关键。现将1982年的研究结果总结如下。一、研究方法本研究分四组10个处理,即:(一)秧田作法——设干耕、干整、干作畦;水耕、水整、作畦晒板;水耕、水整、作畦不晒板三个处理,以水耕、水整、不晒板的为对照。(二)不同隔离物——设切碎红花鲜稿、
It is the most economical and effective method of seedling raising at present. It has the advantages of low cost and good economic effect, and has the advantages of high seedling emergence rate, seedling growth, short stature, early-onset and early maturity, and has the physiological basis of high-yielding seedlings. However, the effect of play, especially to reduce the “stick plaster” and improve the rate of seedling, it is the key to the success of plastic film seedling technology. The findings of the 1982 study are summarized below. First, the research methods The study divided into four groups of 10 treatments, namely: (a) seedling practices - set dry, dry, dry 畦; hydroponic, water whole, as 畦 drying board; hydroponic, For the three non-drying plate processing, hydroponic, water whole, non-drying plate as a control. (B) different spacers - set cut fresh safflower fresh draft,
