How much does silicon fertilizer work on rice? When to apply silicon fertilizer to rice

Effect of silicon fertilizer on rice growth.

Spraying time: depending on the degree of cultivated land pollution, you can choose to spray foliar fertilizer 1-2 times from the vigorous tillering period of rice and wheat to the heading period; Choose a sunny or cloudy day to spray around 4 p.m.

Dosage description: about 1 bottle per mu each time; Artificial spraying needs to be mixed with water 50-100 times; UAV spraying with water to hollow 5-10 times; Foliar sprays are applied. Based on the principle of foliar dripping, the number of spraying should be increased according to the degree of pollution of cultivated land.

Precautions for the use of foliar fertilizer in rice:

1. When using, it should be prepared and used, and the prepared cadmium reducing foliar inhibitor should not be stored for a long time.

2. Foliar spraying is required with a sprayer with good atomization effect.

3. Do not use it in rainy days, if it rains 24 hours after spraying, it needs to be supplemented. Do not spray when exposed to the sun to avoid burning the leaves.

4. Do not spray with pesticides or other foliar fertilizers, so as not to affect the effect.

5. Store in a ventilated and cool place. When spraying, you need to wear gloves, masks, and work clothes to prevent the entrance from entering the eyes, and splashing ** should be quickly cleaned with water.

6. Keep out of reach of children's rental barricades to prevent children from eating by mistake.

Rice silicon fertilizer should be combined with nitrogen, phosphorus, potassium, zinc and other burning fertilizers as the bottom fertilizer and applied to the soil, it is best to sprinkle before tillage or before water rake, and there is fertilizer in the whole layer after water rake. The standard dosage of silicon is 1 to kilogram per 667 square meters (1 mu).

When silicon fertilizer is used as top dressing, the best effect is applied 30 days before heading. When applying paddy fields, the water layer should be shallow, and deep ploughing should be carried out immediately after application, so as to promote the integration of soil and silicon fertilizer.

The amount of silicon fertilizer is about 30 50 kg per mu, but it must be noted that silicon fertilizer must be applied in combination with nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, and silicon fertilizer must not be used to replace nitrogen fertilizer and phosphate fertilizer or a kind of fertilizer. Silicon fertilizer can improve the soil and is cheap, and it is best to apply it continuously.

Silicon fertilizer is best applied together with organic fertilizer such as straw, farmhouse fertilizer, green manure, etc., and the silicon fertilizer is mixed with organic fertilizer when ploughing the ground, which can not only accelerate the decomposition and decay of organic fertilizer such as straw, but also improve the effectiveness of silicon fertilizer. In addition, the effect of silicon fertilizer will be better if it is soaked with farmhouse manure for a period of time before application.

With the development of agricultural production, the role of fertilizer in production is increasingly recognized and valued by the majority of farmers. How to rationally apply medium and trace element fertilizers has become a simple, easy, economical and effective measure to increase production in production. With the continuous improvement of rice yield, the effect of increasing silicon fertilizer in rice is gradually emerging, especially in areas where the soil available silicon content is not abundant, and the application of silicon fertilizer to rice has been an effective measure to stabilize and increase yield.

The amount of silicon fertilizer is about 30 50 kg per mu, but it must be injected into Ruyi silicon fertilizer must be infiltrated and applied in combination with nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, and must not be used to replace nitrogen fertilizer and phosphate fertilizer or a certain fertilizer. Silicon fertilizer can improve the soil and is cheap, so it is best to use it continuously.

<> change the situation of the plant: after the rice absorbs silicon fertilizer, the wax will form silicified cells, and the silicized cells can improve the strength of the cell wall of the rice, which will make the plant grow taller and the stems and leaves more erect; At the same time, the light-shielding situation of rice will change significantly, which is conducive to the ventilation, light transmission and accumulation of organic matter in the wisdom of Tian Hongju. Improved lodging resistance:

Silicon can enhance the strength of the stem at the base of rice, and its lodging resistance can be increased by more than 80%.
