Management measures of Taoyuan in early spring

The management of peach orchard in early spring should focus on ditch management, fertilizing, filling gaps, application of remover and other work, which is conducive to the formation of strong buds and lay the foundation for high yield and high quality of peaches in that year.

1. Clear ditch and refresh water

Low-lying terrain, heavy soil viscosity and waterlogging are the main factors restricting the high yield and high quality of peach trees, especially less Rain Water since the second half of last year, and it is very likely that there are too many Rain Water this year. If the drainage of Taoyuan gully system is not good, it will seriously damage the roots and weaken the tree potential. Therefore, for the dragons and peripheral ditches of Taoyuan, it is necessary to organize labor to clean up thoroughly, remove weeds and silt, ensure smooth drainage, and deepen the border ditches where possible.

2. Apply spring fertilizer early according to the situation of the tree

For mid-ripening varieties with many fruits last year, such as Baifeng, Fenglu, Taqiao and other peach trees, as well as some weak trees, those who have not applied wax fertilizer since last winter should apply spring fertilizer as early as 1 kilogram of imported compound fertilizer and 1.52kg of domestic compound fertilizer per plant. The ring ditch is applied, and the soil is covered after application. Fertilization time: the end of February.

3. High branch grafting

The wild peach trees in peach orchards of more than three years old can be grafted by high branch grafting. Generally, the survival rate of branch grafting is higher, and the root system is perfect and the rhizome is strong, which can blossom and bear fruit in the second year and harvest yield. The yield in the third year is similar to that of trees of the same age. Can be grafted, the time is controlled at the end of February and the beginning of March, the survival rate is the highest at the beginning of sap flow. Trees with poor varieties can also be grafted and purified.

4. Timely application of scavengers

Stone-sulfur mixture has a good killing effect on overwintering scale insects and aphids, and has a special effect on preventing tree shrinkage disease of peach trees. It is not only the only control agent of the disease, but also against peach brown rot, anthracnose and so on. The use time is between the beginning of March and March 10th. When the flower bud scale is slightly red, the spray concentration can be reduced to 3 Mel 4 degrees. For large households with more than 10 mu, it is better to burn stone-sulfur mixture, with high utilization rate and low cost. Small households can spray stone-sulfur mixture crystal, every 1.5 Rue 2 packets (400 grams / pack) into a backpack bucket of water.

5. Fill the gap and transfer in time

Under the premise of deep ditches and high beds, the newly planted peach orchards this year should be planted in late February. For the lack of trees or wild peach seedlings in the one-or two-year-old peach orchard, make up for the lack of planting in late February, and apply good base fertilizer, water enough live trees, which is beneficial to the early development of living trees.
