The study found out that in 2009, the outbreak situation of the jujube of the jujube A chirpworm is also known as a clip-mouth worm, a beak worm, and a gory-mouth worm. It is a skin-eating pest that eats newly-grown bast skins from jujube trees, which are tamped after grafting and peeled after girdling. They are a good place for them to live, to marry and to peel off fresh growth tissue (bast), is their delicious food. According to the comparison of the major forestry diseases and insect pests in China in 2008 and the end-user technicians' data on wintering bases of major diseases and insect pests at the end of the year, combined with less precipitation in winter 2008, the temperature is higher than last year, and the repeated occurrence of extreme weather is conducive to the reproduction of the nail worms. Characteristics, found in 2009 jujube an epidemic situation. The major pests that harm the jujube tree are the dark and dodgy spots. The gray and dark spots belong to the lepidoptera and moth family. They invade the tree body through various wound tissues and harm the callus and phloem. As the jujube trees are reclaimed every year, the young A-mouth organization provides an annual event venue for the nail worms. The dark spotted beetle (Aphis gossypii) occurs four to five generations a year. The mature larvae live in the trees and begin to move in late March of the following year. In early April, the larvae emerged at the end of April. The first generation of larvae occurred in early May. The second and third generation larvae jeopardize jujube trees the most. The researchers call for: The peasant technicians and the majority of jujube farmers must face this natural disaster. They must adhere to the principle of “prevention first, comprehensive prevention and control†and take measures before or at the stage of the occurrence of pests and diseases to make full use of various factors that inhibit pests and diseases. To create conditions that are not conducive to the occurrence and harm of pests and diseases, based on agricultural control and physical prevention and control, taking biological control as the core, scientifically and rationally applying chemical control methods based on the biological characteristics and hazard characteristics of pests and diseases, and controlling pests and diseases in the economic valve. Below the value, to ensure that the quality of jujube fruit meets the relevant standards.

1. It is forbidden to open A and avoid creating insect disasters. Before and after the Mang species, when most jujube trees on the winter jujube hang and flower 5-8, the best quality “head flower†is in full bloom at this time. There are many fruit set, long fruit growth period, large head, consistent maturity, and high yield. Good quality and high commodity value. Zhanhuang County Forestry Bureau technical station, the new home station chief told reporters that they have been engaged in the jujube tree for three consecutive years to promote Kao test, the test results show that: smear "promoting Huawang No. 2" can improve the jujube sitting date rate, The jujube trees once and twice smeared were higher than the control (circumferential two-year jujube without applying Huawang No. 2), and the jujube rate was increased by 111% and 155%; the jujube tree was full-bloomed and smeared at the end of the flowering stage to improve the fruit hang ratio by 14.5. %, but the jujube tree blooming flower less smeared, more fruit drop, more nutrient consumption, flowering at the end of the jujube tree painted more flowers, less fruit drop, less nutrient consumption, more beneficial to the weak tree nutrition tree; jujube tree ring cut two circles Smear "Huahua No.2" once compared with jujube tree without looping, without "promoting Huawang No. 2", the fruit hanger ratio is increased by 100%, and the fruit hanger ratio of "Huahuawang No. 2" is increased by 63% over two rounds of cutting. . Through the comparison of the jujube tree and the use of “Huawang 2†jujube trees discovered by technicians of the technical station of the Zanhuang County Forestry Bureau, it was found that the leaves of the Kaizao jujube trees began to appear yellowish green five days after the armor was opened and continued for 24 days. Days, until the mouth healed well before turning to a strong green, while the ring cut twice plus smear “promote Kaowang 2′′ twice the jujube leaves are always dark green. From the results of the survey of the county technical station on September 8, we found that fruit hangers were almost the same as the two through two treatments, but the rate of fruit cracking was 83.6%, and the fruit rate of using Kawang was only 6.3%, and the use of pro-Kavao delayed the ripening period of 13 days than that of open-harvest fruit, which missed the peak incidence of crusted fruit and effectively prevented the occurrence of custodial diseases. The jujube farmer Zhang Chengwen made a calculation last year. In the same jujube garden, he used the "promoting Huawang No. 2" to produce 865 kilograms of fresh red dates, while the same jujube garden produced a jujube tree. Fresh red dates 738 kilograms, than the open jujube tree increased production by 17.2%, mu gain 1270 yuan.
2, timely picking, fruit thinning. The cores of jujube heads, secondary branches, and jujube hangings, except for the extension of the main branches, were repeatedly toned to reduce nutrient consumption and promote fruit setting. In the middle and late June, fruit thinning is carried out. Generally, each jujube tree hangs 1 fruit, 2 trees of jujube tree hang 1 fruit, and 3 trees hang fruit 1 every 3 jujubes, and the remaining fruits are all dredged. In addition, the physiological fruit drop after fruit thinning was significantly reduced, the earlier the fruit thinning, the lower the physiological fruit drop, the rapid growth of jujube fruit, high uniformity, and good quality, thereby increasing the output of jujube fruit.
3, increase fertilizer material. At the same time as fruit thinning, foliar fertilizer + melon and fruit turbidity is sprayed once every 15 days to enhance tree vigor and promote fruit development. 0.5% urea solution, 0.3% borax and 0.3% dihydrogen phosphate can be used for foliar fertilizer application. Potassium and so on. From late August to early September, when the jujube fruit enters the white mature stage, appropriate application of potash fertilizer can promote the growth and maturity of jujube fruit, facilitate the transportation and transformation of sugar, increase the sugar content of fruit, improve the fruit quality and resist storage. Sex, the specific approach is: foliar spray twice 0.3% potassium sulfate, a 4% of grass ash leaching liquid, each plant roots of winter dates, 0.1 kg of potassium sulfate.
4, to prevent pre-harvest fruit drop. 6-8 weeks before harvest, even spray 2 times 20-30ppm of nitric acid + fruit Zhuang Ti Ling, can effectively prevent the jujube fruit before harvest.
5, timely harvest, timely tree disinfection. After the fruit is harvested, the tree is extremely weak, and if it is not protected in time, the pests and diseases will take advantage of it. Therefore, after the fruit is harvested, it must be treated with 1000-fold solution of the general tree tree plus a moderate amount of Fu magnesium arsenic or lime sulfur to spray the trunk. .
