Management points of the latest early flowering mango tree

Because of the long drought in winter, or the high temperature, it is very easy for mango trees to flower ahead of the Beginning of Spring, leading to early flowering, while before and after the Qingming Festival, it is extremely vulnerable to the threat of overcast and rainy days of ground temperature, seriously affecting pollination and fertilization, reducing fruit setting rate, resulting in reduced production. So how to manage the early blooming mango trees? Let's get to know it with the editor.

1. Remove the spike of flowers

Mango has a strong ability of ear regeneration, which is picked out in time after extraction, and it will be pulled out again in 7-10 days, and it has many branches, short spikes, more female flowers, late flowering and easier fruit setting. Therefore, after the mango has a flower spike in January-February, when the flower ear grows to about 5-10 cm, it should be removed from the base in time to promote it to produce more short clump-like multi-female flower spikes and delay flowering at the same time, which is beneficial to the later yield.

2. Fertilizing and cultivating soil

After removing the flower ear, it is necessary to apply fertilizer in time to provide sufficient nutrients for fruit trees to produce flower spikes. at this time, fertilization is mainly organic fertilizer and high-efficiency phosphorus and potassium fertilizer, generally more than ten-year-old fruit trees, each plant is treated with 25-30 kg of rotten farm manure, 3-4 kg of superphosphate and 1-2 kg of potassium chloride or potassium sulfate. The method of annular ditch can be adopted. After all the fertilizers are fully stirred evenly, the fertilizer is applied into the annular ditch, and then the soil is covered. At the same time, about 80 kg of clear water or retting rotten human and animal manure water was applied to each fruit to promote fertilizer dissolution and transformation and improve fertilizer utilization efficiency. After fertilization, the soil can be cultivated with garbage fertilizer, pond mud, burning soil or other soil fertilizer, and the tree plate can be covered with rice straw or other weeds, which can fix and raise the soil temperature and promote the development of flower spikes.

3. prevention and control of diseases and insect pests

Early flowering mango trees, diseases and insect pests occur especially early, so control must also be early, in order to protect the flower ear, after removing the flower ear, need to be an Lubao, Shibaoke mixture inside and outside the crown every 10-15 days, or enemy kill, Shi Baogong mixture, spray 2-3 times in a row, evenly spray all leaves, with leaf droplets dripping down is appropriate.

4. Spraying foliar fertilizer

After removing the flower ear, foliar fertilizer needs to be sprayed every 7-10 days. 0.2% urea, 0.3% potassium dihydrogen phosphate, 1500 times Shennong chelate fertilizer, or 0.2% urea, 1000 times high efficiency biological phosphorus and potassium fertilizer, and 1000 times Zhuangfengyou mixture can be used for 3-5 times. This can promote the growth of spikes, improve the quality of flowers, and improve the rate of flowering and fruit setting.
