First, the choice and arrangement of the garden: Peach drought, fear of embarrassment. It is necessary to ensure that the trees can be planted on a row, dry land, and flat land. The water and fertilizer are sufficient, and growth is good, but the ventilation and drainage are poor. Therefore, it is advisable to plant the plants in a north-south direction, and it is suitable for ridge cultivation to plant ridges on the ridges. The 50 cm high peach tree prefers to loosen the soil, favoring root growth and nutrient absorption. Due to dense planting and cultivation, trenches with a depth of 60 cm-80 cm x 60 cm-80 cm should be dug, and the mixture of fertilizer and soil should be filled and filled with water. Hillside hilly areas can be planted at equal height.

II. Density and tree shape: The appropriate density and reasonable tree shape are conducive to intensive management, and the early yield is high, which is the trend of modern fruit tree development. The flat land is planted in a “Y” shape with a row spacing of 1-1.5x4 meters. -160 trees. From north to south, the two main branches extend to the east and west, and the angle between the two main branches is about 80 degrees. The result of easy forming and lighting is early and high-yield, high-quality, and can be intercropped in the early stage and easy to manage in the later stage. Hillside hill can be used three main branch happy shape, spacing of 2x3 meters, 111 acres planted.

Third, the planting time and methods: after the autumn leaves to the spring before germination can be, generally better than the autumn spring planting, the root can heal wounds, and can produce new roots, the following year early germination, early pumping, peach The trees are resistant to drought and drought. The roots of the shallow pits should be raised slightly above the surface of the ground and cultivated into small mounds. Nectarine should be eaten fresh, with very early maturing and early maturing varieties as the main products, taking into account mid-late-maturing varieties.

IV. Fertilizer and Water Management: After planting till the end of July, fertilization and irrigation are mainly nitrogen fertilizer. (Water is fed once every 10 days) to promote the growth of the seedlings, and to control the water in later stages, and to restrain the growth of the autumn to facilitate flowering, supplemented by Phosphorus and potassium fertilizers. Colonization of the base fertilizer was mainly autumn. Do not apply water after falling leaves until the fruit matures.

Fifth, plastic surgery and pruning: Peach traditional plastic pruning, to force shaping, heavy short cut mainly. Strong technology, time-consuming pruning, and easy to bald internal warts, the external easy to steep, long-term results, external shift, low output, limiting the development of intensive. The use of "y" shaped plastic, simple tree, easy to trim, easy to learn and easy to understand, the following year can be a large number of results, three-year high yield, fast income.

6. Focus on summer pruning: The plant spacing is 1-1.5 meters, north and south line to planting, then planting saplings so far is about 60 centimeters (the greenhouse is planted shorter) topping, promote new branches, choose the right two adjacent branches as the main branch The angle is about 80 degrees, and the trunk is left with 2-4 auxiliary branches, and the branches are torn to about 30 centimeters to make a temporary result. (The three main branches have a happy shape? "Y" is the same shape. The main branch angle is 120 degrees, and the angle between the main branch and the vertical line is 45 degrees.)

Seventh, focus on cultivating two main branches, leaving no branchlets on both main branches, leaving only branchlets and medium-long fruit branches. The back branches and the competing branches that affect the growth of the main branches are removed in time to maintain the robust growth of the main branches, so that the internal warts are not bald and the periphery is not prosperous. In the autumn, the branches and branches can be expanded in 3.5 meters with two main branches covered with long fruiting branches and branchlets, laying the foundation for the second year's high yield. When the winter is lightly cut or long-term, the individual planting output can reach 5-10 kilograms in the next year. In the summer (early maturing varieties), short cuts, twisted branches, and pull branches are the main components after fruit picking. This results in the branch close to the trunk. To prevent the relocation of the resulting part, the shortest part must be completed by the end of July. After July, the main branch should be thinned, and the large branches on the outside of the light sticks should be removed on the back of the sticks. The winter branches should be cut every year. Branches, branches on the back, dense fruit branches. Moderate short-cut fruit branches, sparse flowers in the early spring, supplemented with fruit thinning, fruit should be moderate.

Chemical control: In the middle of July, 150-300 times of paclobutrazol was sprayed. After 15 days, it was sprayed once again to control the growth of a little autumn and promoted the formation of a large number of flower buds.

Through the above series of management methods based mainly on summer shear, supplemented by winter shear, the annual yield of up to 4,000 kilograms can be achieved in the third year, and the economic benefits are considerable.
