Rice is a crop that absorbs more silicon, rice body silicate content of 5-20%, about 10 times the nitrogen, phosphorus, about 20 times. Rice lack of silicon easily lead to stem slender and weak, easy to fall and easy to infected diseases, pre-silicon so that the number of spikes of rice into a reduction in the late lack of silicon is a reduction in the number of spikelets, rice quality and high yield is not guaranteed, silicon fertilizer on the rice yield increase is generally in the 10~15%.

    With the continuous improvement of rice yield, rice application of silicon fertilizer effect is also gradually revealed, especially in the soil is not rich in effective silicon content of the region, rice application of silicon fertilizer has been an effective measure to stabilize high yield. Here we come to see what benefits of silicon fertilizer applied to rice? How to apply silicon fertilizer to rice?

    Rice application of silicon fertilizer benefits

    1, rice application of silicon can enhance the ability of rice pest resistance

    Rice silicon application enhances the resistance of rice to pests and diseases, and reduces the degree of damage caused by pests and diseases. Rice silicon can improve plant light posture, reduce leaf sagging, improve photosynthesis, the formation of silica cells, so that the stem and leaf epidermal cell wall thickening, cuticle increase, enhance the hardness of the stalks, leaf uplift, stalks clear and upright, developed root system, thus improving the ability to resist diseases and pests. In particular, resistance to rice blast, leaf spot disease, stem rot, rice leaf blight and stem borer, drilling insect resistance is strengthened. 　　

    After applying silicon to rice, the silicon content of the plant increases, and the rigidity of the conduit is enhanced, which can increase the aeration and permeability inside the plant and promote the growth of the root system, and activate the phosphorus in the paddy field water, prompt the phosphorus to run in the rice plant, improve the utilization rate of phosphorus fertilizer, reduce the greediness and collapse due to the application of excessive nitrogen fertilizer, and at the same time can also prevent the rotting of the roots of the rice and the early decline, especially for the eradication of the toxic rotting root disease of the rice has an Important role.

    2, the application of silicon fertilizer can improve saline rice fields and reduce the pollution of pesticides on the soil

    Application of silicon fertilizer on saline rice paddy management has a unique role. Silicon fertilizer contains silica and calcium and magnesium ions, can be quickly added to the large loss of elements in the soil, while these elements in the silicon fertilizer can be a large number of saline and alkaline paddy rice accumulation of sodium ions in the replacement reaction, the formation of new compounds, reducing harmful components, supplementing the growth of rice in urgent need of silicon dioxide and calcium and magnesium ions to enhance the resistance of the rice to increase rice yields and improve the quality of rice. Agricultural pollution comes from people's control of crop diseases and insects. Application of silicon fertilizer can make rice produce a tougher siliconized cells, so that pests are not easy to bite, in order to achieve the reduction of pests and diseases, reduce the use of pesticides, thereby reducing pesticide pollution.

    3, silicon and other nutrients interaction, can be drought, anti-fall, yield effect is remarkable!

    Application of silicon fertilizer can regulate the rice of nitrogen, phosphorus over-absorption, and promote the transformation of flux products to polysaccharide materials to ensure that the high yield of rice quality. For example, improve the silicon and nitrogen ratio of rice can improve the ability of rice to tolerate high nitrogen, reduce due to partial application of nitrogen fertilizer caused by greed, late maturity and collapse, rice in the case of flooding the use of silicon fertilizer can promote the oxidative capacity of the root system, inhibit the over-absorption of iron and manganese to reduce the harm.

    After absorbing silicon, rice can make the rice plant epithelial cells silicification, stalk stout, leaf blade erect, reduce shading, photosynthesis enhancement of 15-20%, about 85% of the resistance to fall, leaf angle narrowing, canopy photosynthesis enhancement, drought and water saving ability to enhance the general water saving of about 30%, 20% to 30% increase in yield. Therefore, in the growth process of rice, it must be timely to supplement silicon fertilizer, as well as nitrogen, phosphorus, potassium and other trace elements, to ensure high yield and high quality of rice!

    Rice silicon fertilizer application method

    The nature of silicon in the soil is stable, poor mobility, fixed in the form of compounds, rice is difficult to absorb, so the application of silicon fertilizer is very important. Rice silicon fertilizer should be applied with nitrogen, phosphorus, potassium, zinc and other fertilizers as a base fertilizer into the soil, preferably before tilling or water harrowing sprinkled, water harrowing after the whole layer has fertilizer.

    In addition, can also be sprayed outside the root, in the rice tillering period mu spraying high efficiency quick soluble silicon fertilizer 100 grams, even sprayed twice, the effect of rice yield is very significant, the general application of silicon fertilizer in rice yield 5-20%. The standard dosage of silicon is 1 to 1.3 kg per 667 square meters (1 mu).
