Cement is sprinkled in the rice fields, but what is the purpose of this cement?

Spreading cement in the rice field has a certain effect on increasing yield. Because cement contains calcium and trace elements, which are required for crop growth, these elements have certain benefits for rice.

The separation of a certain mineral in the cement increases the fertilizer efficiency of the soil, and the rice obtains more nutrients so it grows more lushly, but it should be noted that the cement can not be added more, otherwise the soil will solidify and agglomerate and be detrimental to the growth of rice.

There are two functions, the first is to use cement solidification to reduce water loss. The second is to use the solidification of cement to reduce the growth of weeds.

Cement can really increase rice yields. As a food crop affected by grain**, the farmer is not very interested in growing food, but this grain farmer still wants to win and must do everything possible to increase the yield of his crop. However, everyone has a different approach to this, and the most common is to increase rice yield after applying cement to the rice field.

First of all, we need to understand that the main components of cement are dicalcium silicate, tricalcium silicate, tricalcium aluminate, tetracalcium iron aluminate, as well as a small amount of free calcium oxide, magnesium oxide, sulfide, silicon dioxide and alkali-containing substances. From this, we can see that cement contains a large amount of silicon, and most of the paddy soil in Zhongqin Kongyuguo, especially the paddy soil in the southern region, has the problem of silicon deficiency. Even in areas where there is no shortage of silicon, with the increasing application level of nitrogen, phosphorus and potassium fertilizers, it is necessary to add the right amount of silicon fertilizer.

Secondly, everyone knows that the limestone in cement is calcium carbonate, and this substance is alkaline. It is necessary to know that rice cannot be in soil with too much acid or alkali for a long time during growth. At the same time, we need to know that the application of silicon fertilizer at the booting stage can significantly improve the toughness of stems, reduce the incidence of lodging, and even effectively increase the number of grains per panicle.

Due to the silica in cement, some farmers will choose cement over silicon fertilizer.

In addition, cement is easy to condense after mixing with water, so the cement on the leaves will condense when it encounters water vapor in the air vapor section of the air, hindering photosynthesis, so cement is not conducive to the growth of rice. We can start from the following residue deficit aspects, and we may get unexpected results: fertilization 10 days after transplanting, fertilization for the third time after unpacking, and appropriate increase in fertilizer amount.

Thereafter, fertilizers with higher nitrogen content, such as urea and ammonium nitrogen, should be applied in stages, while fertilizers with higher phosphorus and potassium content should be applied during the filling phase.
