Greenhouse strawberry fertilization method

Abstract

The invention discloses a greenhouse strawberry fertilization method. The method comprises the steps that 1, in the step of applying base fertilizer, the base fertilizer is applied before the soil preparation, then the soil is plowed and up ridged, decomposed cow manure is applied per mu for 3000-5000 kg, meanwhile nitrate-sulfur based compound fertilizer is applied in a spreading mode each mu for 100-150 kg; 2, in the step of a first time dressing, after the strawberry young seedlings survive, when two leaves expand, the first time dressing is applied on the strawberry soil, the nitrate-sulfur based compound fertilizer is applied per mu for 10-15 kg, after the compound fertilizer is dissolved in water, the fertilizer is sprayed; 3, in the step of a second topdressing, the second time top dressing is conducted after the shed is covered, the nitrate-sulfur based compound fertilizer is applied per mu for 15-20 kg; 4, in the step of fruit bearing stage dressing, after the bearing of the fruits, when the fruits are expanding, peptide compound fertilizer is top dressed per mu for 15-20 kg, at the stage of fruit bearing, the fertilizer is applied once following half a month; 5, in the step of foliar topdressing, in the flowering period, 0.2-0.4% concentration of urea and 0.2-0.4% concentration of potassium dihydrogen phosphate are applied in a spray mode for 3 times, and 0.2-0.3% concentration of borax is applied in a spraying mode for 2 times, according to half a month as a cycle, meanwhile 0.2-0.3% of calcium nitrate is applied in a spraying mode once both at the beginning of flowering period and at the full blossom period. The greenhouse strawberry fertilization method greatly improves the yield and quality of strawberry, and increases the economic benefits of the growers.

Description

technical field [0001] The invention relates to a greenhouse strawberry fertilization method, which is applied in the technical field of strawberry planting. Background technique [0002] Strawberry needs more N, L, and K in the soil. Strawberry has a shallow root system, strong fertilizer absorption capacity, large nutrient demand and is very sensitive to nutrients. Excessive or insufficient fertilization will affect the growth and development, yield and quality of strawberries. bring adverse effects. Strawberry has very little fertilizer in the early stage of growth, and the amount of fertilizer absorbed gradually increases after flowering. Strawberry has different requirements for nutrients in different periods after seedling cultivation, planting and fruit setting. Therefore, it is necessary to fertilize strawberries according to their own growth characteristics. At present In the market, more and more strawberries are grown in greenhouses, but there is still no systema...

Problems solved by technology

Strawberry has very little fertilizer in the early growth period, and the amount of fertilizer absorbed gradually increases after flowering. Strawberry has different requirements for nutrients in different periods after seedling cultivation, planting and fruit setting. Therefore, it is necessary to fertilize strawberries according to their own growth characteristics. At present In the market, more and more strawberries are planted in greenhouses, but there is no systematic fertilization method, so it has a certain impact on the yield and quality of strawberries, which is directly related to the economic benefits of growers
