The correct way to grow strawberries is from the planting site, planting management, plowing and fertilization, etc. The skills of growing strawberries are covered with plastic film and ventilation operations.

1, the correct way to plant strawberries

Planting site: strawberry planting should choose to have enough light, a little higher terrain, the ground is flat, irrigation and drainage is convenient, the soil is fertile and loose, the previous crop for beans or onions and garlic vegetables land is appropriate, planting before the first weed, extermination of underground pests. Can be sprayed with phoxim emulsion to effectively prevent underground pests.

Planting management: strawberry planting time is generally in late September to early October, planting seedlings to have 5-6 leaves robust unfolding. At the time of planting, you can half a month in advance of each mu of 3000-5000 organic fertilizer and 50 kg of nitrogen, phosphorus and potassium three elements of compound fertilizer, in the fine preparation of the ground into a small raised beds, each bed can be planted in double rows, spacing of 18 cm can be best to choose to take the soil transplantation, and make the inflorescences to keep the same peer in the same direction, in order to facilitate the later matting and harvesting.

Fertilizing: Plowing loosens the soil and facilitates the decomposition of organic matter. 3 shallow plowing should be done from November to December. The first flowering period and the early fruiting of each fertilizer 1 time. Mu of urea 10 kg, 20 kg of phosphate fertilizer, 10 kg of potassium chloride, or 35 kg of three yuan compound fertilizer.

2, the skills of strawberry

Covered plastic film: October to early November, is the end of the strawberry inflorescence differentiation, this time to do a good job of shading management, the general jianghuai area can be covered with film after the winter, so that the temperature in the greenhouse to maintain at 28-30 ℃, the warmer years but also to add a cover in the greenhouse plastic film. Small cold to cold season, the shed temperature should be maintained above 25 ℃, at least 23 ℃ above, only to meet the above temperature, strawberry can grow normally.

Ventilation operation: in November-December to do a good job of ventilation, you can uncover the sides of the trellis in the morning at 10:00 a.m. - 3:00 p.m., to maintain ventilation. In addition, when the humidity of the shed exceeds 70%, it should also be ventilated in time, which is conducive to reducing the humidity in the shed. When the shed is stocked with bees during the flowering period, you can make another nylon wire netting at the two ends of the shed in the large and medium-sized shed, which facilitates smooth ventilation.

Strawberry hornblotch disease control measures

1, pharmaceutical control

Generally, you can use 25% Amexida suspension 1500 times liquid, 3% doxycycline hyclate wettable powder 600-900 times liquid, and other agents to control hornblotch disease. It should be noted that it should be used once at an interval of 7-10 days, 2-3 times in a row, and needs to be stopped 3 days before harvest.

2, agricultural prevention and control

Select the strawberry varieties with high fruiting rate, strong disease resistance, strong growth potential, cold and shade tolerance, such as the All-Star, Baojiaogang early birth and other varieties. It is suitable to plant strawberries in plots with convenient drainage and irrigation and open drainage ditches, and the ditch system needs to be cleaned up after heavy rain to reduce field humidity.

In susceptible areas, it is not advisable to intercrop strawberries and peaches, or sweet potatoes, because peaches and sweet potatoes can transmit the disease to strawberries. At the onset of the disease, you need to remove the diseased plants and leaves in a timely manner, and take them out of the field to be burned, and also apply lime or medicine to the diseased hole.
