The application of the principles of the present invention will now be described in further detail with reference to specific embodiments.
1. Selecting a seedling raising field: the container seedling raising field is selected in the central zone of the planning area, the terrain is flat and wide, the soil quality is excellent, the soil mainly comprises sandy loam, the soil is deep and fertile, the sunlight is sufficient, and the ventilation is good; the traffic is convenient, and the water and electricity energy sources are sufficient; and the distance from the peach tree commodity production area to the place meeting the isolation requirement needs to be matched with a working factory building, a stockpiling room and the like in a seedling raising field.
The greenhouse suitable for container seedling culture has multiple types and can be selected according to the seedling culture requirement, and after the greenhouse framework is installed, a plastic film is covered on the framework to form the greenhouse; covering the greenhouse frame with nylon net or other shading material to obtain the shade. The covering material can be changed at any time according to the seedling raising requirement. The peach seedling bed is placed in a greenhouse and is a movable seedbed capable of moving, the surface of the seedbed is an aluminum alloy net surface, and the support part is a galvanized steel pipe and can be used for a long time in a humid environment. The height of the seedbed from the ground is 80-100 cm (the specific height can be properly adjusted to facilitate operation), and the width of the seedbed is preferably 1-1.2 m.
2. Preparing and bagging nutrient soil: the nutrient soil is prepared from 40% of vegetable garden soil, 30% of sandy soil or fine river sand and 30% of deciduous soil by volume ratio. 4 kg of compound fertilizer (the contents of nitrogen, phosphorus and potassium are respectively 15%) and 2.5 kg of superphosphate or calcium magnesium phosphate fertilizer are also added into each cubic nutrient soil. After manual stirring, fully and uniformly stirring by a stirrer, and bagging.
Manufacturing a frame for placing the nutrition bag: firstly, leveling the land, and then paving a layer of black plastic film on the land. Then, a frame is manufactured, the width of the frame is about 0.8 cm (8 nutrition bags can be discharged in each row), and the length of the frame depends on the terrain. Bamboo piles with the height of about 50 cm from the ground are driven into the two sides of the frame every 4cm, the frame cross beams are tied on the wood piles through iron wires, and the height of the cross beams is slightly lower than that of the nutrition bag. And a space of 0.5-0.6 cm is reserved between the frames for a sidewalk and an operation line.
Placing the nutrition bags: and placing the bagged nutrition bags into the frame, wherein 8 nutrition bags are arranged in each transverse row, and binding and tensioning the two sides of the frame by using small iron wires after every 10 nutrition bags are arranged in each transverse row, so that the nutrition bags are not inclined towards the two sides and the front desk of the frame.
3. Time of planting and sowing
Planting time: the planting in spring is carried out before the peach sprouts, and the planting in winter is carried out in the last 11 th of the month.
Sowing time: in spring sowing, sowing should be started after soil is unfrozen, and sowing should be started earlier in areas with short growing seasons.
4. Planting and sowing method
The planting method comprises the following steps: during planting, according to the technical flow of 'three burying, two stepping and one seedling lifting', firstly, soil is crushed, and is flatly and uniformly buried in holes; secondly, putting the seedlings into the centers of the holes to be righted, enabling the seedlings not to nest roots, then earthing up, slightly lifting the seedlings upwards when half of the seedlings are earthed up, enabling root systems to stretch in the soil, and treading the buried soil tightly; finally, burying the residual soil until the soil is flush with the ground, and performing secondary treading. And (3) building planting rings with the diameter of about 1 meter around the peach seedlings, irrigating planting water, sealing soil, and covering mulching films to preserve soil moisture.
The sowing method comprises the following steps: firstly, on a flat seedbed, marking out and opening seed holes according to the plant row spacing or marking out and opening seed ditches according to the row spacing, and then uniformly dibbling seeds in the holes or ditches. And immediately covering soil after sowing, wherein the thickness of the covered soil is 3-5 cm. Covering with plastic film, fixing the covering material on the seedbed to prevent the covering material from being blown away and scattered by wind.
5. Method and time for grafting
The grafting method comprises the following steps: budding with xylem (also called T-shaped nested budding).
Preparation before grafting: irrigating fertilizer and water once 5-7 days before grafting. 1-2 days before grafting, cutting off lateral branches of the stock seedlings 20-25 cm away from the ground. The scion is spring shoot with plump crown and no disease and pest damage, and the grafting tool is disinfected with 1% sodium hypochlorite before scion picking and before and after grafting.
Budding with xylem is a method of budding in a mosaic, which can also be used when it is not convenient to cut buds. Grafting: the diameter of the stock seedling at the height of 15-20 cm above the ground is more than 0.4-0.6 cm, and grafting can be carried out. The Lasa is suitable for grafting in spring and autumn, and the survival rate is good. Generally, the survival rate of grafting is better in the next year of 3-4 months after the stock seedlings are transplanted, and in 8-9 months. Is suitable for large-area seedling culture. The buds of the scions are cut from top to bottom, a cut is horizontally cut from the upper parts of the buds downwards, the bud pieces can be taken off by transversely beveling the lower parts of the buds, the length of the bud pieces is 1-2 cm, the width of the bud pieces is different, and the bud pieces are determined according to the thickness of the scions. The phloem of the stock is cut off from the upper surface to the lower surface of the selected smooth part in parallel, but the phloem is not cut off completely, so that the size of the cuts of the scion and the stock is similar, the cambium is aligned up and down, left and right, and is firmly bound by a grafting film to be beneficial to survival. And cutting off the rootstock after the scion survives.
Grafting time: 3-4 months and 8-9 months.
6. Time for transplanting stock seedlings
The most suitable transplanting time is 3 to 5 months. When transplanting, the stock seedling is held by the left hand, the bamboo chip or the small spade is held by the right hand, a small hole is punched in the middle of the nutrition bag, then the part below the root neck of the stock seedling is placed in the hole, the main root of the stock seedling is straightened and cannot be bent, the surrounding nutrition soil is tightly pressed by hands, the nutrition soil is tightly combined with the root system, and meanwhile, the stock seedling is kept upright and cannot be bent and does not incline.
7. Management of stock seedlings after transplanting
Pouring root fixing water: and (4) after transplanting the stock seedlings, timely irrigating water, and repeating for 2-3 times. And (3) manually irrigating for the first time to ensure that the relative water holding capacity of the nutrient soil reaches 70-80%. Sprinkling irrigation may be used later.
Righting the stock seedling: the oblique stock seedlings appearing in the planting, watering and other processes need to be righted. The method comprises the steps of supporting seedlings by a left hand, inserting the tips of right fingers into nutrient soil in the oblique direction of the seedlings to slowly support the seedlings, gathering the surrounding nutrient soil to the root necks of the seedlings, and properly compacting the gathered nutrient soil.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
