1, site construction: generally recommended to choose a well-drained, deep sandy loam soil for planting; in the planting ground combined with deep plowing on the base fertilizer; deep plowing planting ground leveling, digging planting holes, planting holes spacing of 3mX8m: the base fertilizer, including 200 parts of animal manure, 80 parts of grass fertilizer, 15 parts of calcium superphosphate, 25 parts of ammonium carbonate, urea, 40 parts of and potassium chloride, 5 parts of.
2, planting: selected good growth of yellow peach grafted seedlings into the planting hole, the depth of planting in the grafted parts of the following 3-5cm, backfill fine soil, compression, leveling, drenching the root of the water, fixing the drainage ditch;
3, shaping and pruning: planting of the year when the main stem grows to 40-50cm when the trunk is set, using the three branches of the natural open-ended canopy, the main branch open angle of 50-60 degrees, leaving 3 on each main branch, the main branch of the main branch of the main branch, the main branch of the main branch of the main branch of the main branch, the main branch of the main branch, the main branch of the main branch of the main branch. The main branch opening angle of 50-60 degrees, each main branch to stay 3-4 open angle of 70-80 degrees of the deputy main branch, new shoots in 40-50cm when centering to promote the development of secondary shoots, secondary shoots in the 35-40cm when centering again, to retain the pendulous branches, thinning out the strong long upright branches.
4, fertilization management
juvenile trees: planting 1-2 years of juvenile trees, every 35-40 days to apply a nutritional special fertilizer, 150kg per mu;
adult trees: 3 times the fertilizer: sprouting fertilizer, 2kg of nutritional fertilizer per plant; strong fruit fertilizer in the hard core of the pre-substantiality of the fertilizer, 3kg of nutritional special fertilizer per plant; fruiting fertilizer, fruiting 2 weeks before the picking of the nutritional special fertilizer 2.5kg per plant; the fruiting fertilizer, 2.5kg per plant; the fruiting fertilizer, 2 weeks before the picking of the nutritional special fertilizer, 2.5kg per plant. Special fertilizer 2.5kg;
Wherein the nutritional special fertilizer includes 150 parts of bio-organic fertilizer, 30 parts of urea, 30 parts of soybean meal, 2 parts of ammonium carbonate, 35 parts of calcium superphosphate, 15 parts of diamine sulphate, 10-15 parts of dihydrogen phosphate, 4 parts of zinc sulphate, 3 parts of ammonium molybdate, 12 parts of glycine hydrochloride:.
5, flower and fruit management
Thinning::a, fruiting branch length 15cm, the top of the branch outside the range of 5cm of flowers are all thinned;
b, fruiting branch length 45cm, the base of 5-10cm within the range of flowers are all thinned;
c, fruiting branch length 45cm, the base of the 10-20cm range of flowers are all thinned:
c, fruiting branch length 45cm, the base of 10-20cm range of flowers are all thinned:
c, fruiting branch length 15cm, the top of the branch outside the range of 10 cm of flowers are all thinned. p>
The fruiting branch in the upper part of the sparse androgynous flowers, retaining androgynous flowers down, androgynous flowers down the lack of flowers to retain androgynous oblique flowers, lateral flowers;
Thinning of fruits: the first time in the first fruit thinning after 3-4 weeks after the blossom drop, in addition to removing the disease and insect fruit, malformed fruits, and fruit, weak fruits, the removal of fruit towards the sky, the first to retain the fruit of the fruit drooping growth, fruit tops down the fruit; the second time in the fruit Into the hard core period, an average of 120-130 fruits per plant, single fruit weight requirements in the 160g or so, weak branches, leafless branches do not leave fruit, sparing the development of abnormal fruit, fruiting branches at both ends do not leave fruit, short fruiting branches to stay 1-2 fruits, in the fruiting branches to stay 2-4 fruits, long fruiting branches to stay 4-6 fruits, fruit spacing to maintain more than 6cm;
6, pest and disease prevention and control
In general, you can take measures to reduce the occurrence of pests and diseases by cutting out diseased and insect branches, artificially catching aspen, removing dead branches and leaves, turning the tree disk, covering the ground with straw, and whitening the trunk;
According to the biological characteristics of the pests, you can take the method of baiting and killing the pests with sugar and vinegar solution, yellow boards, black lights, and insect nets;
Use of biogenic pesticides and mineral pesticides: spray 3-5 pomme degrees of thiosulfate once after the fall of the leaves and once before the budding of the buds. 5 pome degrees of rock sulfide; yellow peach after blossoming to before leaf fall, with 75% metribuzin wettable powder 800 times to prevent anthracnose; with 70% agro-streptomycin 3,000 times sprayed 2-3 times in a row to prevent and control bacterial perforation disease: to scrape off the colloid, and then 5 pome degrees of rock sulfide to coat the spots of the method to prevent and control the gum disease; 10% imidacloprid wettable powder 3,000-4,000 times sprayed to prevent and control Aphids, heart-eating insects.
In summary, if farmers and friends want to grow a good quality, high yield of yellow peaches should master the correct cultivation and management techniques and management methods, I hope this article can help you.
