水稻是喜硅作物 ,其生长发育需要大量的硅素。土壤中能被水稻利用的有效硅含量相当低 ,只有通过硅肥的施用 ,才能满足水稻生长发育对硅素养分的需求。在水稻栽培中 ,特别是在高产栽培中 ,移栽期每亩施用含枸溶性硅 2 0 % (其中水溶性硅 5% )的多效硅肥 8kg ,能显著促进水稻根系的发育和对其他养分的吸收 ,改善水稻的营养状况 ,增强水稻的抗倒、抗病性能 ,改善后期光合条件 ,促进后期光合产物的合成与积累 ,使有效穗增加、结实率和千粒重提高 ,增产效果较好
Rice is a hi-silicon crop, its growth and development need a lot of silicon. The effective silicon content in soil that can be used by rice is quite low. Only through the application of silicon fertilizer can we meet the demand of silicon nutrient for the growth and development of rice. In rice cultivation, especially in high-yielding cultivation, application of 8kg of pleiotropic silicon fertilizer containing 20% of citric-soluble silicon (5% of water-soluble silicon) per mu in transplanting stage can significantly promote the development of rice root system and the other Nutrient absorption, improve the nutritional status of rice, enhance the anti-down and disease resistance of rice, improve late photosynthetic conditions and promote the synthesis and accumulation of late photosynthetic products, so that the effective panicles increased, the seed setting rate and grain weight increased, and the yield was better
