What if the rice is damaged by medicine?

Rice is one of the most important food crops in Southeast Asia. Its strains can be divided into two categories: upland rice and rice. The former is mostly planted in mountainous areas or dry land, while the latter is widely planted in paddy fields. In the process of planting, what if the rice is damaged by medicine?

I. what if the rice is damaged by medicine?

If there are many spots on rice after drug damage, which is close to withering or the whole plant is close to withering, all the water in the field should be released immediately, change part of the fresh water into the field, increase fertilizer, and supplement the nutrition lost due to pesticides. If the herbicide is sprayed by mistake, a large amount of water should be sprayed in the field immediately, the herbicide on the rice should be washed away, and the water should be changed repeatedly to reduce the pesticide concentration in the field.

Second, the reasons for the late ripening of rice.

1. Nitrogen fertilizer

Excessive nitrogen fertilizer will affect the growth of rice, resulting in rice can not absorb nutrients normally, resulting in nutritional imbalance in rice. To the later normal mature period of rice, it is still constantly absorbing nutrients, resulting in the phenomenon of greedy green and late ripening, which not only can not increase the yield, but also will decrease.

two。 Light

If rice does not have enough light time, it will lead to a decrease in photosynthesis of rice. Rice leaves too much nutrients, which will be absorbed and transformed all the time, resulting in greedy green and late ripening. And the rice is too dense, the lower rice leaves squeeze each other, can not accept the light, lack of light, resulting in greedy green late ripening.

3. Moisture content

After transplanting rice seedlings, we must ensure that the water in the rice field is at least as high as people's ankles, so as to ensure the normal growth of rice. Lack of water will cause the seedlings to be unable to absorb nutrients normally. Rice ripens late and leaves yellowing too late. Of course, there should not be too much water, otherwise it is easy to cause rice retting.

In addition to the actual consumption of rice, the stalk can be used as fuel, straw sandals, straw mats and raw materials for making paper, and it can also be used as dry material for cattle and horses; Lemma (that is, grain husk) can be used as fuel; bran is a good feed for livestock.
