In recent years, although the strawberry planting area has developed rapidly, most of the farmers lack of cultivation and management techniques for strawberries, resulting in severe cropping and continuous cropping, resulting in some diseases of strawberries. In addition, due to a series of problems such as increased soil-borne diseases, nutritional imbalance, and physiological disorders, strawberry growth retardation or seedling growth after colonization resulted in a reduction in strawberry yield. Coupled with the frequent occurrence of extreme weather in the winter and the abuse of hormones, it often results in frozen receptacles and abnormal fruit. In view of the current problems in production, a simple and efficient cultivation technique is recommended for fruit farmers.
Selection and colonization. The selection of high-quality seedlings is the key to planting survival, and the selection of appropriate local varieties should be based on different regions. Colonization often results in low survival rates due to hot weather. Improve the survival rate method: Bi-care 5000 times plus badew Ling dipping 0.5-1 hours can improve the survival rate and reduce the occurrence of soil-borne diseases.
Seedling management. After colonization and survival, because of the high temperature, it is easy to cause seedlings to grow long. At this time, attention should be paid to timely removal of old leaves, stolons and axillary buds, in order to regulate the hormone balance in plants. Sealing the net can reduce the temperature, which is conducive to flower bud differentiation, but it is not conducive to rooting. In this case, Bihu 7500-8000 times spraying or 20,000 times of drip irrigation can be used to strengthen the roots, suppress leggy, and combine with trace elements such as B, Zn and Fe to promote flower bud differentiation.
Flower and fruit management. The low temperature and short days after entering the late autumn are conducive to flower bud differentiation. The quality and quantity of flower bud differentiation are the basis for the next year's high yield of strawberries. If the seedlings grow vigorously, the root treatment can be carried out to avoid prosperous growth. After budding, Bijing 3 grams watered 30-45 kilograms of spray, which can promote uniform flowering and uniform fruit size, and has the effect of promoting early maturity, improving quality, and increasing sugar content. On December 15th, 2008, the sweet Charlie fruit was sprayed at the Green Dulin Technology Demonstration Garden in Lixinzhuang Village, Shandong Village, Pinggu Town, Pinggu, Beijing: the first fruit set was neat, the second fruit began to bud, and the fruit was large. The fruit began to be harvested, with a single fruit weight of 40-50 grams and a sugar content of 11%. Did not spray Bi-care fruit, the first set fruit is not neat, the fruit just started to mature, 35-40 grams of single fruit, sugar content of 8%.
Pest Control. Due to the high temperature and high humidity in the greenhouse, gray mold, powdery mildew, leaf spot, and verticillium wilt often occur. When the disease occurred, it was used to protect the animals 15,000 times, 10%, or 50% Sekyrin. Bijing can improve the efficacy of pesticides, inhibit germination of spores, and promote cell repair after disease. Insect pests mainly include aphids and red spiders, and 10% imidacloprid and 2% avermectin can be used to prevent spraying. Drugs are forbidden 20 days before harvest.
Fertilizer use management. Strawberry cultivation has a long growing time after colonization. Before the planting, the former fruit farmers often apply a large amount of farmyard fertilizer, and sometimes they are unripe farmyard fertilizers, often accompanied by diseases and nematodes. Some ammonium bicarbonate can be combined to reduce the occurrence of pests. After the planting, if the phenomenon of fertilizer damage and burning seedlings can be used Bijing 5000 times plus amino acid fertilizer spray can promote seedling recovery. Before winter flowering, because the temperature is low, it is not conducive to pollination and fruiting and often appear malformed. At this time, using Bijing 5000-7500 times to spray with boron leaves can reduce the production of malformed fruit. In addition, due to nutritional imbalance caused by leaf yellowing or dry burning and other phenomena, you can use 75% of Bi-protection leaf spray or 20,000 times irrigation roots to promote root development, to alleviate the symptoms of deficiency.
