How to plant and manage pomelo trees 1, and prepare soil for ditching.
First, the plot planted with pomelo trees is ploughed to a depth of 30 cm, and then ditches with a width of 1 m and a depth of 65-70 cm are drawn, and sufficient base fertilizer is applied in layers, and the bottom layer is covered with straw, branches and leaves, turf, etc. Compost and cake fertilizer are applied to the upper layer, and finally the soil is filled and buried, and the soil surface is 20-30 cm higher than the ditch surface.
2. Scientific colonization
Pomelo trees grow vigorously, the crown is broad, and the planting density should not be too high. There are 45 plants per mu on slopes above 20 degrees, 40 plants per mu on slopes above 10-20 degrees, and 35 plants per mu on plots below 10 degrees. Planting time should be chosen on cloudy or sunny nights.
3. Fertilization management
For young pomelo trees, the absorption fertility is weak, so it is enough to apply organic nitrogen fertilizer once a month from March to July every year, such as human feces, decomposed manure, cake fertilizer and so on. In order to promote the growth of new shoots and accelerate the formation of crown, while adult trees are mainly based on available nitrogen fertilizer with phosphorus and potassium fertilizer.
4. Dressing and shaping
After the seedlings of the happiness tree are planted, choose 3-4 strong branches as the main branches, and smooth all the other branches. When the plant is elongated to 40 cm, the top is topped in time, and the clustered branches that cross, overlap and disturb the tree shape are cut off, so that the remaining side branches can be fully illuminated.
