The cultivation and management techniques of economic crops are closely related to the yield and quality of economic crops. Under the premise of protecting environmental resources and maintaining idyllic ecological balance, scientific and rational economic crop cultivation and management can promote the sustainable development of agricultural health in China.
1. Application of phytohormones: In the process of cultivation of economic crops, the principle of the action of phytohormones should be effectively used to effectively serve agricultural production. For example, ethylene ripening, auxin weeding, cultivation of fruitless fruits, and real-time suppression of crop apical dominance have all achieved very good results.
2. Application of biological control: The application of biological control technology meets the requirements of food safety. For example, the use of black light to kill some of the phototaxis of pests; the use of natural enemies of pests for predation; the use of insect hormones to control pests; the use of mutation and other genetically modified species, etc., to cultivate pest-resistant crops, etc., to promote pest control .
3. Application of reproductive control technology: At present, in the agricultural production, the next generation is usually bred by means of grafting, cutting, and other nutritional breeding methods to preserve the good traits of the parents. For example, rapid propagation of flowers and fruit trees, and cultivation of disease-free plants.
4. Adopting Advanced Science and Technology to Cultivate Superior Varieties In the course of improving economic crop varieties, the use of biological breeding techniques can effectively increase the yield and quality of crops and bring high benefits to farmers.
In short, the cultivation and management techniques of economic crops should not only be combined with actual conditions, but also adapted to local conditions, but also with the continuous development of agriculture, make appropriate adjustments to meet the needs of development.
