Winter management techniques of loquat

Loquat is a common fruit, the fruit is rich in nutrients, but also has the main cough moistening throat, and as winter enters, most fruit trees enter winter, but loquat is at this time before flowering. At this time, management is more important. Let's take a look at it together with Xiaobian.

1. Thinning flowers and fruits

Because loquat has more flowers and a long flowering period, it consumes a lot of nutrients. If it is not thinned in time, a large amount of nutrients will be consumed during flowering and fruiting, resulting in weakening of tree vigor, resulting in smaller size, smaller fruit and worse quality, which seriously affects economic benefits. Therefore, in order to save nutrients, overcome the big and small years, improve yield and quality, we must carry out thinning flowers and fruits according to the actual situation. Flower thinning is generally carried out when all flower spikes are extracted. The flower spikes of adult trees are larger, and the earlier the flower thinning, the better. Generally, the flower thinning amount is controlled between 30% and 50%. And because loquat florescence is long, so the result generally has to wait until February to go, fruit thinning is first to disease and insect fruit, abnormal fruit and injured frozen fruit thinning, then thinning dense fruit, keep the same size fruit.

2. Apply winter fertilizer

When loquat plants sprout flower ears in November, 25kg of decomposed farm manure and 3kg of calcium superphosphate should be applied to each plant, and 6-8 radial grooves with depth of 15cm, 10cm and width of 20cm can be dug at the periphery of tree crown. Fertilizers are then sprinkled into the ditch and covered with soil, which can increase the nutrition of the tree, improve the cold resistance of the tree, promote more flowers and improve the fruit setting rate, and lay a solid foundation for the high yield of the next year.

3. Prevention of freezing injury

Loquat florescence in winter, and winter sometimes rain and snow cold weather season, if do not pay attention to cold protection measures, then will make flowers and trees by freezing damage, thus affecting the fruit set rate, so in addition to applying sufficient base fertilizer on the basis of cold and frost protection measures. Irrigation can be done in orchards before low temperatures, which can improve cold resistance, and can also cover plastic film to keep warm and moist. It can also be painted white on the trunk in November to reduce the night temperature difference, avoid bark freezing crack, enhance cold resistance, prevent it by smoking when frost occurs, spray plant cytokinin and fruit antifreeze before freezing injury to improve the freezing resistance of flowers and fruits.

The above is the introduction of loquat winter management technology, I hope to help you, want to know more related knowledge, please pay attention to us.
