工厂化温室育秧具有科技含量高、生产规模大、育秧成本低、节种省工等优点,培育出的秧苗均匀、健壮、整齐。在重庆地区可以减轻倒春寒等不良天气的影响,实现早播早栽为后期避开高温伏旱天气影响提高稻米品质奠定基础,但是在温室育秧在苗期管理上应注意以下几点。一是温室育秧与露地不同,秧盘对水分的缓冲能力有限,播种后床土水分处饱和为宜,水分过多易发生烂种。二是层式育秧架上下层之间温度、采光差异较大,要根据秧苗生长发育的情况调换秧盘的位置,使所有秧盘采
Industrialized greenhouse cultivation of seedlings with high technology, large-scale production, low cost of planting seedlings, saving the provincial section, etc., nurturing the seedlings uniform, robust and tidy. In Chongqing, it can alleviate the adverse weather such as late spring cold, and early planting and early planting can lay the foundation for avoiding the influence of high temperature and drought weather and improving the quality of rice in the later period. However, the following points should be paid attention to in the greenhouse seedling management. One is the greenhouse seedling and open field is different, the tray of water buffering capacity is limited, sowing soil moisture at saturation is appropriate, too much water prone to rotten species. Second, the level of the upper and lower shelf seedling temperature, lighting vary greatly, according to the growth and development of seedlings transplanting the location of seedling tray, so that all seedlings pan mining
