Studies Of The NEL Bioactive Fertilizer On Rice Growth And Effect

NEL bioactive fertilizer is a sort of liquid biological and leaf fertilizer, produced by Korea NEL Biotech Co. Ltd. Its main active component is IAMC (Ionized Alkali Mineral Complex) . The effect of this fertilizer on the growth and development, main traits, grain quality and lodging resistance were analyzed after being applied in different growth period of super hybrid rice, 88S/747. The main results were as follows:1.The effect of NEL bioactive fertilizer on rice germination percentage, seedling rate and earbearing tiller percentage were obvious. The germination percentage, seedling rate and earbearing tiller percentage of seeds, treated with NEL bioactive fertilizer, increased 5.4%,3.32% and 3.92%, respectively.2. Applying NEL bioactive fertilizer could clearly lower the height of seedling, promote the seedling transverse growth and new root growth. The sequence of influencing seedling quality was the young plant period> soaking seed>seedling period, thus, the idea period of NEL bioactive fertilizer application to rice seedling quality was the young plant period.3.Applying NEL bioactive fertilizer in rice tiller stage can promote rice tiller, Tiller Number in peak period was increased 7.9% against the control. The idea period NEL bioactive fertilizer application to rice tiller was the rice tiller stage.4. Applying NEL bioactive fertilizer can enhance the productive tiller percentage, tiller number and seed setting rate, and increase the yield. The yield could be high-significantly raised 5.4% against the control at the tillering , booting stage and heading date. The earbearing tiller percentage, seed setting rate and panicle number per plant could be high-significantly raised 7.4%, 7.0% and 1.1/plant, respectively, against the control at the optimum dealing period of this fertilizer application.5. The effect of NEL bioactive fertilizer on rice leaf age, growth period and grain quality were relatively low.6. Spreading NEL bioactive fertilizer in rice booting stage and heading date could obviously increased rice culm lodging resistant index, strengthen the ability of rice lodging resistant. The crude fiber, all-silicon and potassium could be high-significantly increased 4.5%,4.1% and 4.1%, respectively, against the control at their optimum dealing period of this fertilizer application.
