Abstract

The invention relates to a potato nutrient solution and a potato cultivation method. The nutrient solution comprises the following components: macro elements namely NH4NO3, KNO3, MgSO4.7H2O, KH2PO4 and Ca(NO3)2.4H2O, and microelements namely MnSO4.4H2O, H3BO3, ZnSO4.7H2O, Na2MoO4.2H2O, CoCl2.6H2O, CuSO4.5H2O, FeSO4.7H2O, KI and Na2-EDTA. The purposes of shortening production period and increasing yield are achieved by adjusting nitrogen, phosphorus and potassium in the macro elements of the nutrient solution before the potato seed blooms and after the potato seed blooms; the mass concentrations of three reagents containing nitrogen, phosphorus and potassium in the nutrient solution before blooming are as follows: NH4NO3 is 223-309mg / L; KNO3 is 657-951mg / L; and KH2PO4 is 340-380mg / L; the mass concentrations of the three reagents in the nutrient solution after blooming are as follows: NH4NO3 is 214-253mg / L; KNO3 is 479-751mg / L; and KH2PO4 is 386-430 mg / L. The potato seed prepared by using the formula of the nutrient solution is short in production period, low in cost and large in number of born potatoes; the final yield and various physiological characteristic indexes are improved; the drought resistance capability is obviously improved.

Description

Technical field: [0001] The invention relates to a potato nutrient solution and a potato cultivation method, in particular to the most suitable nutrient solution formula and cultivation method for aerosol-cultured potato seed potatoes in the early flowering stage and the late flowering stage in a greenhouse. technical background: [0002] Although my country's potato planting area ranks first in the world, the yield is not ideal. The potato variety is single, the cultivation technology is relatively backward, and the development of new cultivation technology is slow. Due to land problems such as soil erosion and soil degradation, the research on soilless cultivation technology is imperative. Aerosol cultivation technology adopts continuous production and standardized management. It is not affected by climate and environmental factors, can efficiently produce various economic crops, improves land utilization, and promotes the development of facility agriculture. The potato a...
