Strawberry is a kind of fruit with very rich nutrition. Because of its simple cultivation, convenient management, low input production cost, high yield, and good return, it is recognized by growers. The following is the related technology of strawberry cultivation.
First, cultivating seedlings
In mid-August, the robust seedlings that were previously grown on the stems of strawberry cultivars were selected and transplanted to open seedbeds or plastic rakes for nursery. The nursery bed soil or rammed soil was required to have good water retention and air permeability, and it was necessary to cover the shade net after the strawberry was transplanted to cool down.
Second, planting
Before the planting, the soil in the colonization greenhouse was ploughed. At the same time, the Mushi smelting manure 3000-4000kg, compound fertilizer 50-60kg as a base, and then for hoe, hoe width (even ditch) 1 meter, 6 meters wide standard shed can be 6 畦, 畦 trench depth 25 ～ 30cm. In the middle and late September, the new leaves were selected for normal development. Symmetrical lobule, thick green leaves with thick petiole, large leaves, robust growth, and good seedling yield.
Third, temperature control
Normal daytime temperature is controlled between 25-28 °C, not more than 30 degrees, and 7 degrees in the evening is appropriate. The initial flowering period is 25 degrees, and the flowering period is 23 degrees. Between late December and the end of January, when the temperature of the shed is lower than 5 degrees, a small arch shed membrane should be installed in the shed, and a three-layer membrane insulation should be used at extreme low temperatures. The humidity in the greenhouse is controlled below 80% before flowering, and it is appropriate to control flowering to fruit enlargement at 60%. To prevent the onset of high temperature and high humidity, spray 800 times liquid of “new high-fat film†emulsion once every 10 days for a total of 2 times. In April of the next year, the temperature has significantly increased, and the surrounding membranes on both sides of the greenhouse can be removed to increase the amount of ventilation. This will bring about cooling and dehumidification and extend the fruit picking period.
Fourth, fertilizer and water management
According to the growth of strawberry, it was supplemented with phosphorus and potassium fertilizers and multiple trace elements. There should be sufficient water throughout the growth process, and the soil moisture during the flowering period can be slightly dry, and more water is required during the vigorous growth period of the strawberry and the berry expansion period. Irrigation can be carried out in combination with fertilization. The fertilizer is dissolved in water and formulated into a solution of about 1000 times. After the spring of the second year, as the temperature rises, the production rate is accelerated. To prevent the acidification of strawberry fruits, potassium fertilizer should be applied to apply about 0.3 kg of potassium sulfate per mu. In addition, in the flowering, young fruit, fruit expansion period of spraying "Zhuangguodiling" plus 0.3% -0.5% urea plus 0.3% potassium dihydrogen phosphate, strains of urea 0.1-0.2 kg, improve the quality of grouting.
V. Pest Control
The main pests are aphids, leafhoppers, gray mold, powdery mildew and bud blight. For locusts, red spiders can spray 10% imidacloprid 4000-6000 times, 2000-2500 times to death net. Botrytis cinerea is most prone to occur in high temperature and high humidity and vigorous growth of strawberry. It can be controlled by 800 times of 50% quick keratin, and the effect is very good. For bud blight, pick old leaves, ventilate and transmit light, and spray 1000 times of polyoxorubicin or 600 times of aqueous solution of captopril every other week.
Since the strawberries in the greenhouse have been listed early, the income is very considerable. Therefore, the management technology of the greenhouse strawberry is the key to early harvest and early benefit.
