Sweet nectarine has a smooth, hairless surface, bright red color, fruit crisp and hard aroma, storage and transportation, easy management, high yield, and stable production; popular with consumers. The sweet nectarine planted trees for 1 year, fruited for 2 years, and produced about 15 kilograms for 3 years.
First, use the barren slope and change the civil engineering garden. 1 Soil requirements: Choose convenient land, smooth or gentle slopes with light, deep, fertile, loose, well-drained sandy loam, and a slightly acidic soil garden with a pH of 5.5-6.5. 2 Planting time: It is appropriate to plant nectarine after falling leaves at the end of autumn or before germination in early spring. 3 Planting density: Flatland spacing is 3 meters and 4 meters, gentle slope spacing is 2.5 meters and 4 meters. 4 Planting: 1 meter wide, 0.8 meter deep, filled with a layer of topsoil at the bottom of the hole, 25 kg of fertilizer per hole, 1 kg of phosphate fertilizer, 25 kg of farmyard fertilizer, 10 kg of weeds, a layer of soil A layer of fertilizer, and then move the sweet nectar seedlings into the center of the hole, the roots spread to the four sides, use the fine soil to cultivate the roots and necks of the peach seedlings, and then gently practise with the foot, the soil will be a straw hat type, higher than the ground 20 centimeters to prevent the sedimentation of water, and after planting soil, fill the roots with water. 5 plug tray coverage: After nectarine seedlings were planted, we covered the trays with weeds to keep the soil moist and improve the survival rate of the seedlings.
Second, spraying boron during flowering and increasing the fruit setting rate of nectarine. In the flowering stage, 0.1% borax was used for 3 consecutive sprayings and sprayed twice. It was also possible to release the bee at the flowering stage. For every 100 peaches, 1 group of bees were stocked, the bees were pollinated, pollination and insemination were improved, and fruit setting was improved.
Third, reduce fruit loss. When Hua Xie 3/4, with gibberellin 1 gram plus compound anti-droplet 0.5 gram plus urea 50 gram plus potassium dihydrogen phosphate 50 gram against water 20 kilograms mixed and sprayed on the crown 1 time, Hua Xie 25 days physiological fruit drop period Spraying the crown 1 times can effectively control the shedding of young fruit.
Fourth, leaving enough plugs, a reasonable inter-species. Peach trees are afraid of the shade, bogey species of sorghum, corn, wheat, to avoid shading competition fat, outside the canopy dripping line, to plant legume crops or vegetables is appropriate, spring, summer cultivation of soybeans, mung beans, peanuts, watermelons, autumn and winter The cultivation of beans, peas, and vegetables will help the nectarine grow robustly.
Fifth, scientific fertilization, compensation and fertilization. According to the amount of fruit production 3-4 times to compensate for fertilizer, in the management of fertilizer and water, so that "light fertilizer is applied, before the promotion of control", in mid-February application of a budding fertilizer, the application of farmyard fertilizer 25 kg plus urea 50 grams Add 100 grams of superphosphate and 100 grams of potassium sulfate, mix and apply. In May, re-applying a strong fruit fertilizer, the strain applied 50 kg of urea and 50 grams of urea, 150 grams of superphosphate and 100 grams of potassium sulfate, or 300 grams of leaching liquor from plants. In the hard core stage, urea 150g plus potassium dihydrogen phosphate 100g plus Penshibao 5ml or 0.1% Lufenweiga plus 50 kilograms of fresh water for spraying the crown once. In late June, apply the farmyard manure 25 kilograms plus urea 50 grams plus superphosphate 100 grams plus 50 grams of potassium sulfate. After mixing, dig a ring groove or pig slot-shaped opening outside the canopy drip line, 25 cm deep, and wide. 25 centimeters, covering the soil the next day after the application, covering 20 centimeters above the ground. At the same time, use 1 gram of paclobutrazol 1 kg, once every 7 days, spray twice, control the shoot tip too long, shorten the internodes, the leaves turn green thick, glossy, vegetative growth is controlled, reproductive growth will have A better material basis to promote flower bud differentiation to create conditions for the next year's high yields.
6. Deeply plough the soil and thicken the soil. In shallow soil areas, deep ploughing and soil improvement are required. Drainage trenches are added around the garden. The roots of the nectarine tree should avoid standing water. The roots should breathe more strongly to prevent accumulation of water, and the deep trenches should be planted to ensure smooth water systems. At the same time, soil loosening, good ventilation, and conducive to root growth.
Seven, found pests, timely prevention and treatment. The common anthracnose and brown rot of nectarine trees damage the flowers, buds, leaves, new shoots, fruits, and fruit surfaces into dark brown and atrophy. In the onset stage, the tree crown spray is sprayed with Baume 0.3-0.5 degree lime sulfur. . Bacterial perforation disease, leaf lesions polygonal reddish-brown or brown lesions of the leaf tissue, the onset of the disease with 65% of the Sen Zinc 0.5 kg watered 400 kg spray canopy 1 times. From May to July, peach aphid (Peach blossom heartworm) harmed the fruit and sprayed a tree crown with 500 kg of water to kill pine pollen. In the middle and late July, a little leafhopper (small green dust) harmed the leaves and affected photosynthesis. The water was sprayed with 800 times of the phosphorothiosulfate twice (once in seven days).
Eight, reasonable plastic surgery. According to the characteristics of sweet nectarine has a strong light, the plastic method is to dry in the main trunk of seedlings 50-70 centimeters before the planting of sweet nectarine seedlings in the winter or next spring, and leave it in the next 20 centimeters. 3 staggered distribution of robust buds in different orientations, allowing them to be extracted into 3 main branches, and the rest of the toppings or removals. When 6-7 axe shoots are drawn from the main branches, the crowns are basically formed, and the main branches are straight or properly bent. Make the main branch angle 50-60 degrees, forming a natural happy shape. The extension branch of the backbone branches left 50-70 cm short cuts (the clipped buds left the outer buds), and the retraction renewed the shoots from the base to renew the shoots. For the upright leggy branches, pull branches for shaping, increasing the angle of opening to ease the growth potential, from vegetative growth to reproductive growth, reaching early knot early abundance.
