1, selecting the seed planting

First we need to choose a good variety, according to the local environment to choose the appropriate growth, and to ensure that there is the ability to pollinate each other. After choosing a good seed, then choose a thick layer of loose soil, drainage and irrigation normal sandy soil for planting. Control the spacing between plants and rows, and dig a good planting hole. Then apply about 10kg of farmyard fertilizer to each planting hole. Seedlings are mainly about two years old, and the cultivation time is preferred in spring and fall. Autumn is usually the best time to grow seedlings because they heal faster and have a higher survival rate. The height of the seedlings is maintained at about 120 cm, the roots are intact, and after planting, they are well watered and then covered with mulch.

2, fertilizer management

September of each year in the soil deep turning combined with the application of adequate fertilizer, farmyard manure-based, mixed with an appropriate amount of chemical fertilizer. Young trees fertilizer 20kg or so, large trees fertilizer 40kg or so. Before the tree buds, each tree should be hole applied about 130g of urea and the appropriate amount of compound fertilizer. Then in the flowering period, pay attention to spray the appropriate amount of foliar fertilizer to promote fruit growth and improve the fruit set rate. After each harvest, we should pay attention to applying the appropriate amount of nitrogen fertilizer to promote the tree to restore growth. Then in the flower buds sprouting before to water a big water, into the fruit expansion period and the new growth period, but also to appropriate watering, and to water enough freezing water, to promote the papaya tree overwintering. Excessive water should also be timely drainage.

3, plastic pruning

Papaya tree shaping method to the natural round head type based on the stem 75 cm or so, choose about 3 new shoots reserved for the main branch, the main branch growth direction can not be the same. The distance between each main branch is maintained at about 15 centimeters. Then do a good job of summer pruning, summer pruning to wipe buds, pulling branches and centering mainly to improve the permeability of the crown, to promote the growth of the summer tips. It is also necessary to carry out winter pruning, winter pruning is mainly to expand the crown. The main branches reserved for the first year are shortened, retaining about 35 centimeters. Young trees can not be heavy pruning, mainly thinning too dense and too long, cross overlapping and other branches.

4, flower and fruit management

In the planting of papaya trees, in order to improve the yield of papaya, to ensure that the yield is stable, in the establishment of the papaya garden should pay attention to planting the right amount of pollination trees. The ratio of planted varieties to pollinated varieties is controlled at about 4:1. So after this, we have to do a good job of flower and fruit management, and appropriate flower and fruit thinning should be carried out during the flowering period, especially in the big year. Fruit thinning objects to branch head fruit, deformed fruit and other undesirable fruit. Retain the base of the branch, the center of the fruit. The distance between the fruits is kept at 20cm do, to improve the yield and quality of the fruit.
