1 Yellow peach is planted on loose fertile land with high terrain, sufficient sunshine, deep ploughing before sowing, sufficient fertilizer application and drainage ditch. Yellow peaches are mainly rootstock seedlings, and the rootstock variety is generally Maotao. After the peach pit is layered, the kernel is taken to accelerate germination, and the scion with excellent comprehensive properties is selected. Take the vegetative branches at the periphery of the middle part, remove the leaves and leave the petiole. Select a robust bud head to cross 1 knife at its upper part until it reaches the xylem, then cut the xylem at the lower end of the bud upward to the transverse incision, and then stick the cut scion. Bud grafting is carried out in the middle and early June and from mid-August to mid-September. The grafted seedlings of the former can leave the nursery in the same year, and the sprouting tillers should be pulled out in time to promote seedling germination. The latter will become a semi-finished seedling that year, and the rootstock will be cut off 0.5cm away from the bud grafting part in the next spring to cultivate grafted seedlings.
2 165438+ 10 is planted from October to March of the following year, mainly in autumn, and the peach seedlings are planted before the soil is completely frozen after defoliation, so that the seedling emergence is delayed quickly and the survival rate is high in the next spring. The density should be determined according to the conditions and varieties of the garden, the way of shaping and pruning, and the management level. Generally, 450~750 plants/hectare should be planted (1 hectare is 15 mu). The depth of the planting point should be 40 ~ 80 cm. Choose strong seedlings (try to choose one-year-old seedlings, which is shorter than the period with sprouts 1 year, and the molding will be shortened by two years, and the fruit will be produced in the second year), plant at the same level, and apply 50 kg of organic fertilizer/hole and calcium superphosphate 1 kg/hole to achieve one layer of fertilizer and one layer of soil.
3. After defoliation, before freezing, deepen and expand the Taoyuan hole in combination with applying base fertilizer in autumn to improve the physical and chemical properties of the soil, and turn it outward every year or every other year, with a depth of 40-60 cm, so as to minimize the root damage, especially the backbone roots, until the soil between plants is turned up completely, tidy up the tree tray, backfill it with organic fertilizer and fill it with frozen water. After rain or irrigation in the orchard growing period, intertillage and loosen the soil to a depth of 5~ 10 in time.
Cm. Wheat straw, wheat bran, corn straw, hay, etc. It can be covered under the canopy, with a thickness of 10 ~ 15 cm, and 2 cm of soil is pressed on it.
The main pests and diseases of yellow peach are peach anthracnose, peach brown rot, peach fruit borer, pear fruit borer, peach aphid, liriomyza sativae and so on. Pest control should actively implement the policy of "prevention first, scientific control", advocate biological control based on agricultural control and physical control, and scientifically use chemical control technology according to the occurrence law of pests and diseases to effectively control pests and diseases. In the control of peach anthracnose, phosphorus, potassium fertilizer and organic fertilizer should be the main factors in peach growth period, supplemented by urea. Drainage, reasonable pruning, improve ventilation and light transmission conditions, and do a good job in cleaning the orchard in autumn. Cut off pests and dead branches and remove dead fruits.
