Nectarine energy-saving pillarless plastic film solar greenhouse cultivation and success. I. Cultivation Management Before Shed Construction The test site is located in the demonstration park of the Linguo Science and Technology Park in Shanting District, Zaozhuang City. The area of ​​a single shed is 584.8m2, and the shed is 5m, a total of eight sheds. Selected to plant special early sweet nectarine, early ruby, Huaguang, early red and so on. Planted at the end of March, with a spacing of 0.8m2m, covered with black plastic film after planting. 1, before the promotion of post-control: planting from seedlings to early July, strengthen fertilizer management, promote rapid growth of the crown. After mid-July, the fertilizer was strictly controlled, and 15% paclobutrazol 200 times was sprayed for 15 days to inhibit vegetative growth and promote flower bud differentiation. 2. Pruning: For the greenhouse greenhouses, when shaping, the south can use two main branches naturally happy shape, the northern high should use a small crown natural spindle. When the new shoot grows to 30cm, it starts picking the heart and picks up the heart twice a year. The result is a short cut of the cultured branch and the elimination of erect shoots. 3. Shi Jifei: From September to October, each plant used 5-10kg of chicken manure, plus 0.2kg of potassium sulphate, followed by irrigation. Second, the construction of greenhouse The greenhouse is a pillarless plastic solar greenhouse suitable for Shandong. With a span of 8.6m, a length of 68m, a ridge height of 3.2m, a back wall height of 2.4m, and a back slope length of 1.5m, the shed body is constructed with double hollow bricks. Rolling the grasshopper with an electric roller shutter takes about 10 minutes each time. One person can operate 2-3 booths at the same time. The double layer of grasshoppers is covered with a plastic film to increase the temperature of the shelter to prevent rain and snow. Third, after the shed management 1, the temperature and humidity control: buckle shed heating time is December 20, the initial warming should be carried out slowly. The other two critical periods of greenhouse temperature management are the flowering period and fruit expansion period. If the humidity in the shed is too high, watering can be controlled and ventilation can be performed. If the humidity is too low, ground watering or watering can be performed. 2. Flower and fruit management: Adopt auxiliary pollination to increase fruit setting rate. And sparse fruit thinning, pruning the growing season, foliar spray fertilizer. 3, fertilizer and water management: According to the characteristics of peach fertilizer growth requirements of fertilizer in time fertilizer and watering. The predominant nitrogen was in the early stage and phosphorus and potassium were the main components in the later stage. Fourth, after the film removal management The nectarines formed in the greenhouse can not undergo normal flower bud differentiation. Therefore, more than 80% of the new shoots should be cut back or retracted after the fruit is picked, and the new shoots should be promoted as the result of the next year. At the same time, post-harvest fertilizer and water management should be strengthened. V. Pest Control Diseases mainly include bacterial perforation, perforation of brown spots, etc. They are sprayed with 70% thiophanate-methyl WP 800 times and 65% zein Zn WP 500 times. Insect pests mainly include locusts, red spiders, and so on, which can be used to purify 3000 times 10% of the net. Sixth, benefit In the nectarine seedlings planted in March 1999, the yields in single sheds in 2000, 2001, and 2002 were 1,430 kg, 1814 kg, and 1987 kg, respectively. The fruits were well colored and had a good flavor. The ripening period was 48 days and 60 days earlier than the open season. Compared with other facilities, nectarines are easy to manage, have high yields, high prices, and high profits. Disclaimer: Some articles in this website have been transferred from the Internet.
