High-yield cultivation techniques of strawberry in greenhouse are simple and efficient.

In recent years, with the rapid development of strawberry planting, many farmers have not fully mastered the cultivation and management techniques of strawberry. Continuous cropping and continuous cropping often lead to a series of problems, such as serious occurrence of strawberry diseases, aggravation of soil-borne diseases, nutrition imbalance, physiological imbalance and so on. In strawberry production, slow growth after planting at seedling stage or excessive growth of seedlings are important factors leading to the decrease of strawberry yield. The influence of extreme weather such as low temperature in winter and the abuse of hormones often cause flower receptacle to be frozen and abnormal fruits, which greatly affect the yield and quality of strawberries. In view of the common problems in production at present, a simple and efficient high-yield cultivation technique of strawberry in greenhouse was recommended to farmers. Seedling selection and planting. The selection of high quality strawberry seedlings is the key to the survival of planting. Suitable local varieties should be selected according to different regions. When planting, the survival rate is often low due to high temperature weather, and the seedlings are often replenished, which brings trouble to strawberry producers. Here we recommend a method to improve the survival rate: soaking it with 5000 times solution of "Bihou" plus fungicide carbendazim for 0.5 hours can improve the survival rate and reduce the occurrence of soil-borne diseases. Seedling management. Seedling survival, often due to high temperature, easy to cause seedling overgrowth, at this time should pay attention to timely removal of old leaves and stolons and axillary buds, can adjust the plant hormone balance, cover the sunshade net, reduce the air temperature, conducive to flower bud differentiation, but not conducive to rooting; can be used "Biyou" 7500 to 8000 times foliar spraying or 20000 times drip irrigation to promote root and seedling growth, combined with trace elements such as boron, zinc, iron and so on to promote flower bud differentiation. Flower and fruit management. After entering late autumn, with the decrease of temperature, low temperature and short day light is beneficial to flower bud differentiation, the quality and quantity of flower bud differentiation is the basis of high yield of strawberry in the next year, if the growth is exuberant, root cutting treatment can be carried out to avoid vigorous growth; leaf picking treatment can also affect vegetative growth and reproductive growth, generally leaving 4 or 5 strong leaves. After budding, foliar spray of "Bihuo" with 3 grams of water and 30 kilograms of water can promote neat and uniform flowering, uniform fruit size, promote early ripening, improve quality and increase sugar content. On December 15, 2008, in Lvdulin Science and Technology demonstration Park of Lixinzhuang Village, Shandongzhuang Town, Pinggu District, Beijing, "Bibou" was sprayed (variety is Sweet Charlie): six fruits were sat for the first time, all of them were seated, and the second ear fruit began to bud. The fruit is large, and part of the fruit begins to be harvested. The single fruit weighs 40 to 50 grams and contains 11% sugar. In the strawberry orchard without spraying "green protection", the fruit is not set neatly for the first time, and some fruits have just begun to ripen. The single fruit weighs only 35 to 40 grams and the sugar content is 8%. Pest control. Due to high temperature and humidity, gray mold, powdery mildew, leaf spot and Verticillium wilt often occur in the greenhouse. Prevention and control of diseases should be given priority to prevention, ventilation and humidity reduction should be paid attention to, and diseased leaves should be removed in time. Once the disease occurs, "Bi Hou" can be used for foliar spray with 15000 times plus 10% Gao or 50% Sukeling. "Bihou" can improve the efficacy of pesticides, inhibit spore germination and promote cell repair after disease. Strawberry pests are mainly aphids, red spiders, etc., can choose 10% imidacloprid and 2% avermectin spray control. It is forbidden to use medicine 20 days before harvest. Fertilizer use management. Due to the long growth time after planting, many fruit farmers often apply a large amount of farm manure, sometimes immature farm manure, resulting in diseases and nematodes, which can be combined with some ammonium bicarbonate to reduce the occurrence of diseases and insect pests. If fertilizer damage (burning seedling phenomenon) occurs after strawberry seedling planting, spraying with 5000 times of "Bi Hou" plus amino acid fertilizer can promote the recovery of strawberry seedlings. Before flowering in winter, due to the low temperature, it is not conducive to pollination and fruit bearing, and abnormal fruits are easy to appear. Foliar spraying of "Bihou" 5000mm 7500 times with trace element boron can reduce the production of abnormal fruits. Due to the phenomenon of leaf yellowing or dry edge burning caused by nutritional imbalance, "Bihou" can be sprayed 7500 times foliar or 20000 times irrigated to promote root development.
