What is intensive cultivation of rice? What are the advantages?

Intensive cultivation of rice was put forward by Father Henri de Laurani in 65438-0983. The basic idea is that in order to make rice yield higher, each plant must have more tillers and more effective panicles. There are many grains per panicle, and the number of grains is large. In order to make the aboveground part grow well, the underground part must have a strong root system. According to the growth characteristics of rice, rice intensive cultivation system strengthens the individual growth environment of rice plants by strengthening technical measures, so as to achieve "strengthening roots and promoting tillering" and fully tap the individual production potential, thus achieving the goal of greatly increasing production. The main technical characteristics are early planting of seedlings, thinning of single plant, irrigation without water layer, intertillage weeding and use of organic fertilizer. Its advantages are:

(1) has great potential for increasing production. In the intensive cultivation system of rice, technical measures such as interplanting between individual plants, transplanting seedlings, increasing application of organic fertilizer and irrigation without water layer can create good environmental conditions for the robust growth of rice seedlings and give full play to individual growth advantages. The underground part of the plant has strong rooting ability, and the above-ground part has obvious tillering advantage. The highest tiller number and panicle number per plant doubled, the grain structure per panicle was balanced and coordinated, and the panicle type was large. It is a super-high-yield cultivation technique to improve the yield mainly by fully tapping the potential of individual productivity.

(2) Save costs and protect the environment. Seedling raising and transplanting can reduce the cost of seedling raising, and sparse planting per plant can greatly reduce the amount of seeds and transplanting labor. The uncovered irrigation method is a kind of water-saving cultivation. It is emphasized that the application of organic fertilizer provides complete nutrition for rice, and the plants are robust and resistant to pests and diseases, which is also conducive to reducing the use of pesticides and environmental protection. Therefore, while increasing production and income, it can also reduce costs.
