Problems solved by technology

[0003] The core technology of aerosol cultivation is the preparation of nutrient solution. At present, there are relatively few studies on aerosol cultivation of potato nutrient solution. In addition, the same nutrient solution will have different effects on different potato varieties, so there is no special one suitable for potatoes. ideal nutrient solution

Abstract

The invention relates to a nutrient solution for cultivating potato microtubers by greenhouse gas atomization and a cultivation method. The nutrient solution includes: NH4NO3, KNO3, KH2PO4, MgSO4.7H2O, Ca(NO3)2.4H2O, MnSO4.4H2H3BO3, ZnSO4.7H2O, Na2MoO4.2H2O, CuSO4.5H2O, FeSO4.7H2O, KI, Na2-EDTA 37mg and CoCl2.6H2O. After the field planting of potato virus-free seedlings, the nutrient solution is immediately sprayed according to the following spraying internal: spraying 15s every 5 minutes during the first five days after the seeding planting; then adjusting the spraying time by spraying 15s every 10 minutes for 5 days; and finally adjusting the spraying time by spraying 15s every 20 minutes. By the adoption of the nutrient solution provided by the invention, the photosynthesis of potato plants is enhanced; the plant height and stem diameter of the potato plants are obviously greater than those of potato plants cultivated by the prior art; the mineral element content is obviously raised; the final output and quality of the potato plants are better than those of potato plants cultivated by other prior art; potato plants grow under a suitable condition and the production potential ofpotatoes is tapped to the greatest extent; and problems such as long production period of potato core microtubers, low weight per microtuber, small quantity of potatoes per plant and the like are solved. By the adoption of the cultivation method, the production cost is reduced and the validity of the nutrient solution is enhanced.

Description

Technical field: [0001] The invention relates to a nutrient solution for potato cultivation and a potato cultivation method, in particular to the most suitable nutrient solution formulation and cultivation method for aerosol-cultured potato miniature seed potatoes in different growth stages and tuber formation stages. Background technique: [0002] Potatoes are both vegetables and food, and are also good feed for the development of animal husbandry. In addition, potatoes are also one of the indispensable and important raw materials in food industry, pharmaceutical manufacturing industry and light industry. However, due to the poor quality of seed potatoes, the degradation is serious; the potato variety is single , backward cultivation technology and other reasons make my country's potato industry still lacks competitiveness in the international market, and the quality and quality are relatively poor. The potato aerosol cultivation technology can be used to artificially contro...
