Cultivation techniques of one-sided Peach trees

One-sided peach tree refers to a kind of tree shape in which the whole fruit tree is tilted about 45 °to the west or north, so that the plants of the whole orchard fall in one direction. Generally, it is more common in the greenhouse. What are the cultivation techniques of peach trees on one side?

I. selection of land and land preparation

Choose sandy loam or loam soil with high topography, good drainage, leeward to the sun, low groundwater level and loose soil. Then level the ground, spread fully mature organic fertilizer per mu, or use biological organic fertilizer fermented for 1-3 months, generally using 3 to 4 square meters per mu, potassium sulfate compound fertilizer 50kg, calcium phosphate fertilizer 100kg, several fertilizers mixed evenly on the ground, immediately deep turn 20-40cm, fertilizer is best scattered with ploughing, and then rake the ground.

2. Selection of species

Select varieties with large fruit, good color, good quality, large pollen quantity, high self-setting rate, resistance to storage and transportation, and low cold requirement, such as Zhongyou 4, Zhongyou 5, Zhongyou 9, Zhongyou 11 (very early 518), Zhongyou 12, Dazaohong, Red Rose, Huacai, Lichun, Super Hongzhu and so on.

Third, planting density and time

The row spacing of the plants planted in the greenhouse is 0.75-1.8m, 500m or 0.8m-1.8m per mu, 2X2 1.25m-2.5m in the open field, the earlier the planting time, the better. From December this year to late March next year, the greenhouse can be intercropped with grass curtain, melon and watermelon (open field can be intercropped with melons, watermelons, peanuts, etc.). The seedlings are planted in the border above the strip. Centralized management of seedlings in nutrition bags can also be used for open field cultivation in greenhouses. First, seedlings are planted in nutrition bags (old cement bags or convenience bags can be used), and the proportion of nutrient soil is 70% of soil, 25% of sand, 5% of biological fertilizer or fully fermented organic fertilizer. Peach seedlings are planted in the nutrition bag and placed in the greenhouse or small; grow and reshape in the bow shed after 1-3 months.

IV. Post-planting management

1. Timely drying: the tooth seedling (semi-finished product) is cut from the interface to the 2cm. 10cm was left on the interface of the finished seedling. When the new shoot grew to 5-10cm, only one full bud was left, and the other buds were removed in time. From germination to 50cm, the temperature of peach seedlings is 20-26 ℃ in daytime, the highest is not more than 28 ℃, and the temperature at night is not lower than 5-10 ℃. When the seedlings grow to 20-30cm or so, bamboo stalks are planted to tie up the trunk to prevent the wind from breaking.

2. Plastic surgery: the inverted tree on one side of the peach tree is the trunk type, which makes the peach tree grow obliquely. When the new shoot grows to about 50cm, it sends out side branches, and 40cm leaves the first side branch from the ground, and the first side branch grows until 20cm coring, cutting off 10cm and leaving 10cm, promoting secondary side branches. The second side branch is long until 20cm cuts off the 10cm and leaves 10 minutes, and promotes the second side branch, and the third, fourth, fifth, sixth, seventh and eighth side branches are the same as the first and second side branches.

3. Topdressing: when the new shoot grows to 20-30cm for the first time, apply bicarbonate 50-80 jin per mu or urea 20 jin / mu, 30-40cm from the tree evenly, or one side of bio-organic fertilizer, it can also be used as excess water from the process of bio-organic fertilizer production.
