Strawberry greenhouse promotes cultivation, which greatly advances the fruit ripening period. However, some farmers only pay attention to production, neglecting the improvement of quality, or paying attention to it, but they are technically indispensable, thus affecting the economic benefits of greenhouse strawberries. So, how to improve the quality of greenhouse strawberries? In addition to the selection of suitable varieties, the use of virus-free and healthy seedlings and the establishment of the buckle shed in due course must be done as follows:
First, the appropriate temperature to control the temperature and humidity suitable for strawberry fruit development is 18-25 °C, to reach this temperature in the winter and early spring, in the greenhouse can be set in the shed and cover film, and strive to shed temperature during the day to reach 25-28 °C, at night Above 5°C, minimum temperature above 0°C. However, if there is a high temperature above 30°C, ventilate and cool it in time. The soil temperature is suitable to maintain 40% -60%, too large and small will affect the root activity of the strawberry and the fruit's normal growth and development.
Second, Taiwan Fertilizer greenhouse strawberry results in a long period of time, in order to prevent defermentation of premature aging, to re-basal fertilizer, timely top dressing and frequent spray foliar fertilizer. In the fertilization, we must master the nitrogen-enhanced potassium-enhanced potassium (in the case of weak growth, increase the application of nitrogen fertilizer, and the result is increased potassium fertilizer for a long time). In general, the mulching bar of 40 lbs. per mu, and 30 kg of compound fertilizer, 100 kg of calcium, magnesium and phosphate fertilizers. In the middle and late period, spraying spray can spray foliar fertilizer (200 times Greenway 18), can promote the development of the fruit in the middle and later stages, and increase the fruit weight and sugar content.
Third, picking leaves and fruit aging leaves produce less photosynthetic products, and respiratory depletion, adverse growth of strawberries and berry development, the unnecessary occurrence of stolons also consume maternal nutrition. Therefore, the result should be timely removal of the lower senile leaves and early removal of stolons. In addition, the removal of certain high-grade secondary flowers before and after flowering can not only reduce the rate of malformed fruit, but also help concentrate the nutrient supply of low-level secondary flower development, increase fruit size and improve uniformity.
IV. Comprehensive Prevention and Control of Diseases and Insect Pests Diseases and pests in greenhouses are mainly based on agricultural control, supplemented by pharmaceutical control. That is, through the use of virus-free seedlings, high-ridge planting, mulching, irrigated crops, and drought, high humidity and other measures to prevent the occurrence of fruit, rotten fruit. The sick leaves and fruits found in the field must be promptly removed to prevent spread. Chemical control should pay attention to before and after flowering without drugs, so as not to affect pollination, so that more abnormal fruit. To minimize the use of pesticides during the fruit harvest period, the pesticides with low residual toxicity should be selected and the fruits should be stopped within 2 or 3 days after spraying to prevent fruit residues from affecting human health.
V. Timely harvesting of strawberry fruits in greenhouses is mainly based on fresh food, and must be harvested when more than 70% of the fruit surface is red. In winter and early spring, the temperature is low, and it should be harvested when the fruit is 8-9 mature. The temperature rises after the early spring and the harvest period can be appropriately advanced. Picking should be carried out at 8-10 am or 4-6 pm. Do not remove fruits and hot sun so as not to spoil. When picking, take it lightly, pick it lightly, and put it gently. Do not damage the calyx. At the same time, it should be packed and packaged in stages.
