Management of early Spring in Taoyuan
The main results are as follows: 1. the topography of gully drainage is low-lying, and soil viscosity and waterlogging are the main factors restricting the high yield and quality of peach trees. if the drainage of Taoyuan ditch system is not smooth, the tree will be weakened due to wet damage to roots. Therefore, the outlet ditch of Taoyuan should be cleaned thoroughly to ensure that the drainage is smooth, and the ditch should be deepened if possible.
Second, depending on the tree potential, spring fertilizer should be applied early for medium-ripe varieties with more fruit, such as peach trees such as Baifeng, Fenglu, Taqiao, and weak trees that have not been fertilized since the beginning of winter. Fertilizer application rate: imported compound fertilizer 0.5 kilograms per plant, domestic compound fertilizer 1.5 kilograms per plant. The ring ditch is applied, and the soil is covered after application. The fertilization time is at the end of February.
3. High branch grafting can be used to graft wild peach trees in peach orchards for more than 3 years. The survival rate of branch grafting is high, and the rhizome is strong, which can blossom and bear fruit in the second year, and the yield is equal to that of trees of the same age in the third year. The grafting time was at the end of February and the beginning of March, and the survival rate was higher at the beginning of sap flow. Branch grafting can also be carried out for trees with poor varieties.
4. the timely application of stone-sulfur mixture has a good killing effect on overwintering scale insects and aphids, and it has a special effect on preventing fruit shrinkage disease of peach trees from March 1 to 10. When the flower bud scale is slightly red, the spray concentration can be reduced. It is better to burn stone-sulfur mixture for large households with more than 10 mu.
Fifth, in time to fill the gap and transplant newly planted peach orchards, under the premise of deep ditches and high beds, strive to be planted in late February. Yes, in the 2012 peach orchard.

Its cultivation techniques are mainly as follows: 1. Wide adaptability: suitable for growing in fields, fields and hillsides with good drainage conditions. II. Planting specifications: 1. 222 plants planted according to 3 feet ×9 feet per mu;2. 136 plants planted according to 5 feet ×9 feet per mu. More than 60% of pear trees bloom in the same year of planting (in order to facilitate the growth of young trees, all young trees should be removed).
