Strawberry Scientific Management Three Steps
Strawberry is an economic crop with fast results, early maturation, easy propagation, short cycle, and high profitability. Doing a good job in the annual management can make strawberry produce high and stable, with good quality.
First, pre-winter management
After the strawberries are colonized and survived until mid-late November, the following three points of management are noted:
1. Fertilizer application: In mid-October, topdressing N, P, K compound fertilizer or urea by 5-8 kg per acre will promote root growth, increase the number of flowers in the top inflorescence, and increase the ability of plants to overwinter. The second time from mid-November to early December, the amount of fertilizer to be applied is small, and nitrogen, phosphorus and potassium compound fertilizer or urea is applied at 7 kg per mu.
2. Keeping moist: from the late September to the beginning of October, the insulation of the buckle film will begin. In addition to the double cover insulation for the greenhouse and the small arch, the insulation measures such as leaf cover can also be adopted.
3. Weeding pine soil picks old leaves and diseased leaves.
II. Management before and after flowering
The flowering and fruit setting period of strawberry is mainly controlled at 20°C～28°C. In this period, special attention should be paid to the prevention of frost damage during the flowering period, and no temperature below 5°C should occur. Spray 800 times of “new high-fat film†emulsion once every 10 days for 2 times. Antifreeze, cold, keep flowers and fruits.
In the flowering period, young fruit stage, fruit expansion period, spraying “melon and fruit shuangtinglingâ€+0.3%-0.5% urea plus 0.3% potassium dihydrogen phosphate solution, applying urea 0.1-0.2 kg to supplement nutrients needed for fruit growth. , Improve the quality of grouting.
Strawberry fruit is soft and has a long flowering period. Special emphasis should be placed on adopting comprehensive pest control measures. Flowering fruit set and fruit development period without chemical control. Prevention of gray mold, bud blight, etc. are mainly used before flowering, and can be used for quick keratin, thiophanate-methyl, or thioredoxin.
Third, wintering management
Strawberry is a perennial grass plant, and its key period of high yield management is in winter. The key to the winter tube is to do a good job of "three defenses", that is, prevent cold, prevent drought and prevent early flowering.
Before the onset of winter, it is necessary to apply water to prevent the cold.
Strawberries should be managed scientifically during the whole growing period to ensure that the plants grow robustly, and they bloom more, have more fruit set, fruit size, good taste, and high yield.
