温室培育小苗的特点是温度高,秧苗密度大、生长快、生育期短,为了育成整齐、茁壮的秧苗,就必须用催芽均匀一致的种子播种,先使它能够很整齐的出苗,这一点很重要.为了促使种子能够均匀地萌发,就必须提高选种和浸种的质量。尽量选用饱满(千粒重在28克以上)并且发芽势强的种子。充分浸种,使所有种子都吸足水分,消除每粒种子吸水速度不一致的缺点;并从稻壳里溶出妨碍种子发芽的某种物质。这是选种和浸种的主要作用。 Cultivation of greenhouse seedlings is characterized by high temperature, seedling density, fast growth, short growth period, in order to grow neat, robust seedlings, it must be uniformly germinated seeds sowing, it is very neat to make it emerge, it is very Important. In order to promote uniform seed germination, we must improve the quality of selection and soaking. Try to use full (1000 grain weight in more than 28 grams) and strong germination seeds. Full seed soaking, so that all seeds absorb enough water, eliminating the imbalance of water absorption rate of each seed; and from the rice husk dissolve the seed germination of a substance. This is the main role of seed selection and seed soaking.
