Some flower buds on the lateral side of the strawberry and flower buds on the lateral branch, the differentiation was not completed that year, and continued in the spring of the second year. During flowering in spring, flower bud differentiation and lateral branching on the lateral buds differentiated slowly. After flowering, these flower bud differentiations began to accelerate. However, the quality of these flower buds is poor, and as a result, the yield is very low. If the management can be strengthened, the yield can be greatly increased, and the average yield per mu can reach 800 to 1,000 kg. The specific measures are as follows. First, top-dressing watering. In the late period of fruit picking, 15 kg of compound fertilizer and 1 kg of potassium dihydrogen phosphate were collected per acre. Sacrifice was crushed first, then the second fertilizer was diluted with water, and the eyes were poured into the root soil, followed by watering. The fruit enlargement period is also top-dressing watering 1 or 2 times. During this period of drought, pay attention to watering. Second, shading and cooling. From flowering to fruit enlargement period, control the temperature of the greenhouse, 20°C-25°C during the day, and 5°C or more at night. The harvest period does not exceed 25°C during the day and 5°C at night. During the second fruiting period of the strawberry, the temperature has started to rise and large ventilation and shading measures have to be taken. Can lift a curtain cover a curtain, or lift two curtains cover a curtain. Third, the stem leaves in addition to stems. At the late growth stage, when the lower leaves of the plant are horizontal and begin to turn yellow, the base of the leaf also begins to change color, and should be promptly removed from the base of the petiole. Sick leaves should also be removed in time. We also need to remove the weakly growing lateral buds on the plants. Fourth, disease prevention and pest control. 1000 times of methoxy ethyl chloride mercury solution can be used to irrigate and control the root rot, 50% buddriferium 600 times spray to control bud blight, 50% chlorothalonil 600 times spray, and light the smoke at night Shed control gray mold, spraying 70% mancozeb 500 times liquid to control leaf blight, spraying 80% dexamethasone 600 times liquid 50% chlorothalonil 600 times spray, using 70% methyl Topozin spray 1000 times to control powdery mildew, use phoxim 600 times to irrigate the earthworms, mantle and ground tigers, use the pyrethroid pesticide spray to control aphids, use 20% triclosan 800 times spray to control red spider.
