Fruit protection measures of papaya

Papaya can not only be eaten as a fruit, but also can be processed into medicine, and it has a more significant effect on arthritis caused by wind chill. in addition, its plant is tall and can be used as a garden ornamental plant. It has been planted more and more widely in recent years. The phenomenon of falling flowers and fruits planted by some friends is more serious, which has a greater impact on the yield of papaya. Let's take a look at the fruit protection measures of papaya together with Xiaobian.

1. Reasonable pruning

In addition to pruning in winter, pre-flowering re-pruning can further adjust the amount of flower buds of papaya, maintain a suitable proportion of nutrient branches and fruit, cut off the rainy flower buds in time, and retract and renew the weak branches, so that nutrients can be concentrated and the fruit setting rate can be improved. Coring the overgrowing vegetative branches, removing part of the vigorous shoot tip growth points, reducing the synthesis and nutrient consumption of auxin and gibberellin, alleviating the contradiction between vegetative growth and reproductive growth, can significantly increase the fruit setting rate.

2. Spraying fertilizer outside the root

Under the premise of strong tree growth and adequate nutrition supply, spraying trace element fertilizer on plants plays an obvious role in promoting fruit setting, especially for orchards lacking some trace elements. Borax + urea solution can be sprayed 2-3 times at full flowering stage, which can promote pollen germination, pollen tube elongation, accelerate the process of pollination and fertilization, and significantly increase the fruit setting rate.

3. Auxiliary pollination

The seed setting rate of self-pollination of papaya is high, but the seed setting rate of cross-pollination is higher, up to 90%, so it is necessary to configure appropriate pollination trees in production, which has an obvious effect on improving fruit setting rate. However, the pollination quality is affected by the climate, and when the number of pollinated plants is insufficient, artificial pollination is needed. First, pick the budding bell flowers from the sturdy trees and take out their anthers. If it is a small number of plants, you can dip the pollen on the style with a brush. If the number of plants is relatively large, you can make a solution with 20 grams of pollen mixed with 10 kilograms of water, 0.5 kilograms of sugar, 30 grams of urea and 10 grams of borax, and then spray flowers with a sprayer.

4. Thinning flowers and fruits

It is necessary to remove excessive flowers and fruits in time in order to maintain a reasonable load on the tree, and the key points for high yield, high quality and preventing years are generally thinning buds during pruning, thinning buds before flowering, thinning flowers during flowering, and thinning fruit within a week to a month after flowering. Thinning flowers should remove inferior flowers with weak growth and small flowers; first sparse clusters of flowers and dense branches of inflorescences; first on the tree, then under the tree; first inside the crown, then on the periphery. Fruit thinning is the first to thinning abnormal fruit, according to the amount of fruit left, determine to leave a single fruit or double fruit.
