How to prevent deformed strawberries? These practical tips you need to master
1. Releasing bees in the greenhouse during the flowering period. Strawberries cultivated under protected conditions flower early, and there are few flower-visiting insects in the early stage. Therefore, when the first batch of flower buds forms, bees can be released in the greenhouse, with 2~3 boxes of bees per standard greenhouse. The beehives are placed evenly around the inside of the greenhouse, which can achieve a pollination rate of over 95%. The bee release times are 8~9 am and 3~4...

Key Technical Points and Methods for Promoting Flowering in Greenhouse Strawberries
The purpose of facility forcing cultivation of strawberries is to achieve early fruiting and early marketing. The key measures are promoting flower bud differentiation and promoting flowering. Measures to promote flower bud differentiation are implemented during the seedling stage, while after transplanting, flowering must be promoted. The methods for promoting flowering include the following: 1. Temperature and humidity management in the greenhouse. The air temperature inside the greenhouse should be 30 degrees during the day and above 10 degrees at night...

How to scientifically prevent and control strawberry pests and diseases? A full analysis of methods and techniques
Under normal growth management of greenhouse-cultivated strawberries, deformed fruit accounts for 10%-20%. However, when varieties are improperly selected or the ecological environment does not meet the growth needs of strawberries, the proportion of deformed fruit often increases, sometimes reaching as high as about 50%, resulting in reduced yield and low returns. Common deformed fruits include crooked and flat fruit, plump fruit, aggregate fruit, protruding...

Deformed strawberries in greenhouses are caused by two main factors
According to investigation and analysis, there are three main causes of deformed fruit. Taking corresponding measures against these causes can prevent the occurrence of deformed fruit. Too low a room temperature is a common cause of deformed fruit. The optimal temperature for strawberry growth and development is 20-25°C. During the flowering and fruiting period, the minimum temperature must not fall below 5°C. If the temperature is below 5°C...
