Citrus maintains vigor and yields
The main reasons for falling citrus fruit are: poor flower development, lack of nutrition, hormonal disorders, long-term low temperature and rain, lack of sunshine, diseases and insect pests, high temperature and drought, and heavy storms. At present, it is the flowering period of citrus, and at the same time it is the critical period for the citrus to determine whether the citrus can be productive in the current year and the following year. In order to ensure the citrus production, the majority of orange farmers should do the following work. The main measures are: 1. Control pests and protect foliage. Citrus flowering period is the main season for flower buds, red spider, scab, and anthracnose. These pests focus on the damage of new and old leaves and flowers, and destroy the assimilation organs. Before the flowering of the orchard, it is necessary to use high-efficiency and low-toxicity agents for general treatment or treatment. For example, if the flower buds use butyl sulphur and carbofuran, the spider mites use wolfberry, the scab disease uses mancozeb, and the anthrax uses diphenyl ether ring. Azoles and so on. 2. Flowering pruning and controlling shoots. Spending more nutrients, affecting the fruit setting rate. Pruning and controlling shoots during flowering can regulate the contradiction between vegetative growth and reproductive growth, and achieve the purpose of flower protection and fruit protection. 3. Maintain tree vigor and supplement hormones. In the fruiting period of flowering and setting, the vigor of the citrus should be kept weak but not mad. In April and May, the result tree should use the micro-fertilizers and hormones for foliar dressing and fruit preservation, especially for trees with large amount of results. Strengthen the dressing outside the root. The fertilizer-losing tree should be supplemented with adequate fertilizer. Juvenile fruit trees and robust fruit trees, fruiting during fruiting period. 4. Hormones preserved fruit. The plant growth regulators commonly used in citrus flower protection and fruit protection are: anti-dropping agent, 920, and Growin, etc. After the flower is applied, it is sprayed twice consecutively for about 15 days. The effect of cross-use growth regulators is ideal. The use of 920 fruits for lesser citrus varieties is better.
