Can perlite breed rice? Can you make it?

　　Rice cultivation is an important agricultural income in South China, but because of some conditional limitations of rice seedling itself, rice seedling raising is usually the main obstacle to its parsing implementation. This year, because of the influence of low temperature in seedling raising stage, it also has a serious impact on the normal growth of rice, and also affects the process of rice transplanting. In view of this phenomenon, agricultural experts in China have put forward a plan for cultivating rice seedlings in perlite.

　　The main advantage of using perlite to cultivate rice seedlings is that the rice seedlings are not susceptible to disease. The specific way of cultivation is as follows: first, make stalks in the greenhouse, then lay some plastic cloth and other appliances, of course, you can also use seedling trays, spread pearlite in the field about 18 mm, then pull up seeds, attach sand, water nutrient solution, sprinkle out from the greenhouse. There is no need to use herbicides and weeds, because such seedlings can not be sick, perlite does not grow grass. No fertilizer is put on the seedlings because the nutrient solution is sprayed once a week.

　　The use of perlite for rice cultivation not only occupies an absolute advantage in terms of cost, but also the most important resource of perlite in China needs to be vigorously promoted, which will greatly enhance the growth of rice seedlings.
