It is critical that the current flowering and fruit preservation is in progress at the citrus flowering stage. However, the recent continuous low temperature and rainy weather is not conducive to the growth of flowers and fruits.
First, the use of Paulownia (including two efficient and long-acting brassinolide) preservation of fruit. For varieties with severe flowering and fruit drop or low fruit setting rate, spraying boron-based leaf fertilizer (do not have to use for consecutive years) at the beginning of flowering time, flowering and fruiting at 3/4, should be used for flowering and fruit protection. Use 24-D; spray foliar fertilizers 5-7 days after the defloration use Paulownia + Anthocyanin + Green-potassium can effectively reduce the post-flowering fruit drop and carry out large branch cuts after fruiting to protect the weak fruit. Cut.
Second, fertilizer and water management. In late March, many low-temperature and rainy days should clear and clear the drains around the orchard to do a good job of drainage and soil conservation to ensure the normal flowering of the plants. Xie Xie should spend 2/3 of the Xiehua with potassium fertilizer as the main control nitrogen fertilizer.
Third, Lei Lei (flower) control tip. Plants with too many fruits in the previous year and with too little harvesting and late flowering were taken to the 2-4 cm thick spring shoots and stayed weak. According to “three sparse ones†and “five sparse twosâ€, sparse springers It will help to reduce the number of buds or flowering buds if the amount of flowers is too large and the tree vigor is weak.
Fourth, pest control. It is forbidden to spray pesticides during the flowering period of flowering bees. Insect protection and fruit protection in particular to prevent rust spiders attach importance to the prevention of scab disease.
Flowering can increase male pollen vigor by flowering and make female stigma stretched to facilitate pollination; spraying spawning at 80% can control hormonal hormone balance and inhibit the formation of abscisic acid, so that the fruit stalk is not easy to produce isolation layer to regulate auxin. The transfer of young fruit to enhance the absorption of young fruit and nutrient transfer to fast green fruit growth stability greatly improve the fruit setting rate. In recent years, Baohe has been popularized and applied by fruit farmers in the citrus area of ​​Guangdong. For the current low temperature and rainy weather, the majority of growers should use high-quality fruit preserves to ensure the foundation of high yield under adverse weather conditions.
