随着农业耕作制度的改革,近几年来对水稻育苗方法也进行了多次改进,去年在外地先进经验的启发下,我们进行了塑料薄膜温室水稻育苗试验,取得一定成果。初步认为它是一个多快好省的水稻育苗方法,具有以下几个好处: (1)占地少,育苗多:因育苗向空间发展,土地利用率高。 (2)育苗快:由于人为的控制水分、温度和光照,能促使秧苗生长快,育苗周期短,在5月上旬10天左右时间就可以育出第一期苗。 (3)苗质好,返青快,分蘖早:据田间观察,比卷秧返青快,分蘖早,主要是由于温室育的苗根系完整,损伤少,根系活力高。 (4)省薄膜,省肥料,省种子,省劳力:薄膜利用率提高,育苗实现工厂化,减轻劳动强度。
With the reform of agricultural farming system, rice seedling raising methods have also been improved several times in recent years. Inspired by the advanced experience in the field last year, we conducted a plastic film greenhouse seedling raising experiment and achieved some results. Preliminary thought it is a more rapid and better rice seedling breeding methods, with the following advantages: (1) small footprint, nursery and more: because of nursery development to the space, land utilization is high. (2) nursery fast: due to artificial control of water, temperature and light, can promote rapid growth of seedlings, nursery cycle is short, in the first ten days of May can be bred first seedlings. (3) The quality of the seedling is good, the greening is fast and the tillering is early. According to the field observation, it is faster than the seedling returning to greening and early tillering. It is mainly due to the integrity of the root seedling in greenhouse and less damage and high root activity. (4) Provincial film, provincial fertilizer, provincial seed, provincial labor: film utilization increased, nursery to achieve factory, reduce labor intensity.
