Taoyuan early spring management, focusing on rational ditch, make up fertilizers, filling shortages, application of eradicators and other work, is conducive to the formation of strong buds, for the peach production and quality of the year to lay the foundation. 1. The low-lying, clean and clear water of the ditch, the heavy soil, and the waterlogging are the major constraints on the high yield and quality of the peach trees. Especially since the second half of last year, the rainfall has been relatively low. It is very likely that there will be more rain this year. If the Taoyuan drainage system is not well drained, it will be serious. Weak damage to the roots and weak tree potential. Therefore, we must organize the labor force to thoroughly clean up the water and the furrows and peripheral furrows of Taoyuan, remove the weeds and silt, ensure smooth drainage, and deepen the conditions for the furrows. 2. Look at the tree potential. Early Spring Fertilizer Where mid-maturity varieties with more fruits and fruits such as: Baifeng, Fenglu, Pagoda and other peach trees, and some weak trees, they have not applied wax fertilizer since the winter and should apply spring fertilizer early. , Fertilizer amount: 0.5 to 1 kg of imported compound fertilizer per plant; domestic compound fertilizer 1.5 to 2 kg per plant. Ring groove application, cover soil after application. Fertilization time: end of February. 3, high branches grafted peach trees on Taoyuan more than three years, you can use high grafting method to graft. Branches generally have higher survival rates, and the root system is perfect for stout rhizomes. The second year can result in flowering and yield. The third year can be similar to the same age tree. Can be grafted, the time to grasp the end of February and early March, the highest survival rate of sap flow. The trees of poor varieties can also be grafted and purified. 4. The timely application of eradicant lime sulfur agent has a good killing effect on overwintering scale insects and aphids to prevent peach tree shrub disease from having special effects. It is the only control agent for the disease and can also prevent peach brown rot. Anthrax is a good disease and insect eradication agent. The use time is between the beginning of March and March 10, when the bud scales are slightly red, the spray concentration can be reduced to 3-4 degrees. It is better to burn lime sulfur mixture for large households over 10 mu, with high utilization rate and lighter cost. Small households can spray lime sulfur crystals, each 1.5-2 packets (400 g / bag) into a bucket of water. 5. To fill in the gaps in time, this year the new species of Taoyuan will be planted in late February in the context of deep trenches and stilts. For the one-year-old or two-year-old peach orchard seedlings in the Taoyuan, in late February to make up for the lack of planting, and the application of basic fertilizer, watering the living tree water, favorable live tree early hair.
