Causes and Prevention of Malformed Fruit in Strawberry in Greenhouse
In the solar greenhouses and plastic greenhouses, the environmental conditions change greatly and there are fewer pollinators. Abnormally large amounts of malformed fruit have seriously affected quality. First, the cause of malformed fruit 1. Variety differences in the main varieties of strawberry, such as early bred, spring incense, etc. are mostly normal flowers; and some varieties are prone to the phenomenon of short stamens, long pistils, and small and small pollen grains Without germination, it is prone to malformation. 2, Huaguo grade senior secondary flowers prone to female incapacity, can not be fruit set or fruit set. The three-stage sequence flower normally accounts for only 60% to 70% of the normal fruit, and the deformed fruit and non-cared fruit each occupy 15% to 20%. 3. Fertilizer and water management During the flower bud differentiation of strawberry, the low or high nitrogen levels in the seedlings will affect the quality of flower bud differentiation. However, flower bud development period, poor nutrition conditions, insufficient nitrogen fertilizer, strong plant growth potential, and poor flower bud development have affected the Normal pollination. 4. The formation of pollen in sunshine conditions begins about two weeks before flowering. During this period, the lack of sunshine will inhibit the accumulation of starch needed for pollen germination, thus reducing the germination rate of pollen. 5, temperature and humidity low temperature, high temperature or high humidity, can easily lead to the occurrence of abnormal fruit. When the strawberry blossoms, the temperature below 0°C can cause the receptacle to become darker; at 40°C or above, the pollen develops poorly; in the high humidity environment, the anther cannot crack. 6. Insect-infected strawberries are insect-borne flowers that must be pollinated by insects. 7. During the flowering period, the ratio of malformed fruit is increased freshly, especially the flowers that are open on that day have the greatest impact. Second, the deformed fruit preventive measures 1, configure the pollination varieties If the selected varieties of pollen pods are low, should be mixed in a certain proportion of pollen amount of varieties. Such as: All Star and Po early delivery or Fengxiang mixed planting. 2. Strengthen fertilizer and water management In the flower bud differentiation and development stage, adjust the amount of nitrogen fertilizer, and accurately grasp the transplanting period, to prevent the emergence of flower buds with imperfect male and female. 3. Reasonably control the temperature and humidity in the shed to build a greenhouse with good insulation properties. Use mulching mulch to reduce the air humidity. The shed film has a long life and no dripping film to reduce the water droplets to wet the stigma. Use 25°C during the day and keep it above 5°C during the night. Drip irrigation can effectively reduce the air humidity. As long as the surface does not dry during flowering, it generally does not require irrigation. 4. Thinning and thinning fruit timely remove high-level flowers, remove fruit, prematurely whitening small fruit and deformed fruit, and ensure the development of normal fruit, in order to improve the quality of fruit. 5. Bees in the shed during the flowering period should be carried out 5 to 6 days before flowering. The 0.5 mus sunlight greenhouse can use no king bees, 4 to 5 boxes, and the number of bees is more than 10,000. The beehive is placed in the southwest corner of the shed. Box door to the northeast corner. In order to prevent bees from fleeing, the ventilation of the shed film is to be covered with gauze. 6, a timely and appropriate application of pesticides before flowering completely control pests and diseases, enter the flowering period, began bee-keeping, should not spray pest control pesticides.
