SOD Strawberry Cultivation Technology

SOD (superoxide dismutase) is an active enzyme in plants and animals. It can eliminate superoxide anions in the body (this substance can damage genetic DNA and RNA in cells, make the body gradually aging, illness), and has health care. , beauty effects. Sunlight greenhouse SOD, health strawberry is a high-tech product developed and tested by Beijing Sanli Fruit Research Institute. Its fruit is not only large and delicious, but also contains more SOD enzymes that are beneficial to human body. Strawberry 500 international units. SOD strawberries are still in short supply when the market price is as high as RMB 80*/kg. This achievement was listed as "Beijing 9th Five-Star Spark Plan Project" and "Ninth Five-Year Key Development Project" of the Ministry of Agriculture. Its cultivation techniques are as follows:
First, the choice of varieties? Choose early maturity, fruit storage and transportation, good varieties of high yield. The main varieties are BAO Zaosheng, Fengxiang, Virginia and Chunxiang. Seedlings should use robust seedlings with 4 to 5 leaves and 3 to 4 fibrous roots. When the big seedlings are planted, the old roots below the new roots should be removed and the new roots should be kept. ?
Second, soil preparation work? First, we must choose fertile, loose, easy irrigation of neutral or slightly alkaline soil, combined with deep plowing soil preparation before planting, high-quality farmhouse fertilizer per acre 4,000 to 5,000 kilograms, and then leveling the land to do stilts. The centipede is north-south, 10 centimeters high, 40 to 50 centimeters wide and 40 centimeters apart. ?
Third, planting? In late August to early September, after breeding seedlings with micro-ecological preparations were rooted and planted in greenhouses. Strawberry greenhouse colonization period is in October, two rows per plant, row spacing 20 cm, spacing between plants 13 to 17 centimeters, planting about 8000 to 10,000 plants per acre, and timely watering after planting.
Fourth, buckle shed and its management? When the outside temperature is reduced to 8 ~ 10 °C at night, it is necessary to buckle the shed in time, after the shed, pay attention to the shed temperature and humidity regulation, through the ventilation and uncover the straw to adjust the temperature and humidity, so that The temperature is maintained at 8 to 30°C and the humidity is maintained at 60%. After the shed is put together, the topdressing fertilizer is used to pour water once, and chemical fertilizer is suitable for nitrogenous fertilizer. After covering the shed, the mulch must be covered. This can not only increase the ground temperature and promote the decomposition of fertilizers, but also reduce the evaporation of water and reduce the indoor humidity. At the same time, it can also control weeds, keep the fruit surface clean, improve the quality of fruit, and reduce the impact of underground pests on fruits. harm. ?
V. Flowering and result period management One month before flowering, spray two probiotic preparations at intervals of 15 days. After flowering, the plants were controlled at 23 to 25°C during the day and 8 to 10°C at night; the humidity was controlled at about 40%. The appropriate temperature and humidity have a great influence on the quantity and quality of fruit set. In the flowering period, wall bees or artificial pollination (pointing with a brush or cigarette paper) are released to increase the fruit setting rate and reduce the occurrence of ineffective flowers and deformed fruit. ?
Thinning and fruit thinning are the main tasks during this period. From the bud stage, 2 to 3 squid branches per plant, 3 to 5 fruit per squid, 8 to 14 per plant of strawberry, and other fruits as early as possible. . The number of fruit remaining is small, and the economic value is high. In addition, the lower yellow old leaves and diseased leaves should be promptly removed to reduce the growth of stolons. If no breeding is required, the stolons that grow out should be cut off in time to enhance the health of the plants and increase the yield. Flowering pests and diseases are mainly aphids. The use of extermination smoke agents to treat smoked diseases is very effective. ?
During the fruit setting period, the temperature in the shed should be maintained at 20 to 25°C during the day and 6 to 8°C at night. At the same time, chase the fertilizer once, use the ternary compound fertilizer and mix it with 0.2% fertilizer, each 0.5 liters to supplement the water and nutrients. ?
Sixth, maturity and harvest? Sunlight greenhouse strawberry from flowering to maturity takes about 50 days, greenhouse strawberry from flowering to maturity takes about 30 days. When the effective accumulated temperature reaches 600°C, the fruit matures, and the mature mark is that the surface of the fruit turns red and emits a unique fragrance. When picking, the handle should be broken by hand, and should be lightly lifted to remove the deformed fruit, pests and diseases at any time.
