When do you plant rice in the countryside, how long will it take to harvest it, and when will you spread the most pesticides?

Rice originated in tropical Asia, and gradually spread to all parts of the world after it was widely planted in China, and it is also one of the main grains in China. According to different methods, rice can be divided into indica rice and japonica rice, early rice and late rice.

Rice is planted at different times in different places, with some harvesting in one season and one harvest in two. In the north and North China, there is a single crop, and the first crop of rice should be sown before the Qingming Festival, while in the south, the second season will probably be sown around the end of June and the beginning of July.

The growing period of double-cropping rice in northern China is 104 days in the first season and 87 days in the second season, which are generally early-maturing varieties, avoiding winter. In the south, the seeds are probably sown in mid-April, transplanting seedlings in early May, harvesting in late July, and then transplanting late rice immediately, which usually ends before the Beginning of Autumn, and late rice harvest from late October to November.

When it comes to growing rice, pesticides are inevitable to prevent rice planthoppers, rice leaf rollers and rice borer. Well, before spraying the most pesticides, we should first know how many kinds of pesticides are used. Generally speaking, pesticides are divided into weeding and worming, early weeding and late worming. Control should be carried out according to different main pests in different periods, and the use time and concentration are also different in different places due to different climatic environment, but it is generally based on defense and should be used before the occurrence of disease and caterpillar fungus.
