Agricultural vegetable planting technology

What you want to ask is "What is the knowledge about agricultural planting technology?" Agricultural planting technology knowledge is as follows:

1. Breeding and breeding of improved seeds.

(1) Breeding. Breeding is the process of selecting new varieties of animals and plants. It is produced by using natural variations in the original varieties. It can also first create new types by using methods such as hybridization or artificial mutagenesis, and then through selection, breeding, and comparative experiments, Breed new varieties that meet production needs.

(2) Breeding of superior seeds. Improved seed breeding is the process of expanding newly created animal and plant varieties to breed seeds, seedlings, and breeding animals to facilitate their promotion and application in production.

2. Crop planting system.

(1) The cropping system is the overall arrangement of crop production in a unit, which mainly includes crop structure, layout, multiple cropping and planting methods (intercropping or single cropping, rotation or continuous cropping), etc.

(2) This is a relatively complex technical system that has a great impact on agricultural production.

(3) The multi-cropping system centered on interplanting and multiple cropping is popular in my country, which is conducive to making full use of time and space, thus reflecting the characteristics and highlights of China's planting system.

3. Crop cultivation technology.

(1) Cultivation technology is a general term for various field management measures taken according to the growth and development laws of crops during the life of crops.

(2) Crop cultivation technology mainly includes variety selection, agricultural machinery configuration, seed treatment, land preparation, sowing, reasonable dense planting, water and fertilizer management, pest and disease control, harvesting and other links. Good planting technology can play an important role in increasing crop production. play an important role.

4. Balanced fertilization technology.

(1) Balanced fertilization: First, the amount of fertilization must be balanced to produce a certain amount of fertilizer (including chemical fertilizers and organic fertilizers), that is, fertilizers should be provided based on the measured soil fertility and crop yield requirements. .

(2) The second is the balance of nutrient types. The nitrogen, phosphorus, potassium and trace elements needed by crops must be matched in proportion.

(3) Both organic fertilizers and chemical fertilizers are non-toxic and harmless, and their application mechanisms are basically the same. The main difference is that organic fertilizers contain more types of nutrients, but most varieties of chemical fertilizers are one or two. It is composed of various elements. Therefore, the elements must be reasonably matched in fertilization technology.

5. Irrigation and water-saving technology.

(1) Water conservancy is the lifeblood of agriculture. Irrigation (or drainage) and fertilization can increase crop yields.

(2) Irrigation must be carried out in a timely and appropriate amount according to the needs of different crops as well as weather, soil, water sources and other conditions.

(3) We must promote water-saving irrigation technology, put an end to the phenomenon of flood irrigation, and promote water-saving technologies such as furrow irrigation, border irrigation, pipe irrigation, and nozzle, drip irrigation, and seepage irrigation.
