Control methods of peach borer
Peach moth, also known as peach moth, peach spot moth, omnivorous pests, throughout the country have distribution. The larvae harm fruits or seeds of winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate, hawthorn and other fruit trees. When the fruit is damaged, it is full of insect droppings, which causes rot. When it is serious, it has great influence on yield and quality. Prevention and control methods: first, early spring scraping bark, blocking tree holes. Black light was used to trap adults. II. 50% phoxim 1000 times solution, or 50% dichlorvos emulsion 1200 times solution, or pyrethroids pesticide shall be sprayed during adult emergence period and peak spawning period. The first generation larvae were sprayed with 50% chloramphenicol or 40% dimethoate emulsion 1200 times solution at the initial stage of hatching, and sprayed again after 7 days, the effect was good. Third, with 50% phoxim, or 20% pyrethroid, or 90% trichlorfon 0.5 kg plus 100 times of soil and water about 10 grams, and medicine mud, mass into a block calyx tube, not only can control the first generation larvae, but also can control the second and third generation larvae, valid period of 70~80 days. 4. The peach moth has strong tropism to sunflower flower disk when laying eggs. Plant some sunflowers in orchards, lure adults to lay eggs on them after flowering, spray pesticides on sunflowers regularly to eliminate peach moth borers, and also trap pests such as tea wing bugs and white star turtles.

Growing jujube in greenhouse: beauty
Jujube cultivation in greenhouse can advance the maturity of fresh jujube by 40 to 60 days, and planted in the same year, the yield of jujube per mu is more than 600 kg. It can reach more than 1500 kilograms in the second year. The jujube tree itself has the characteristics of the fruit of the same year. The seedlings planted in the greenhouse increased the ground temperature, and the roots healed early, grew fast and sprouted early. In addition, the temperature and humidity in the greenhouse during the flowering period are suitable, the fruit setting rate is obviously increased, while the flowering period of the open field jujube tree is dry, and the fruit setting of the first crop is very few, so the fruit weight and yield of jujube in the greenhouse are higher than that of dew.

The cultivation technique of Tianshui kernel apricot passed the appraisal.
Recently, the project "Development of barren Mountain Resources in Tianshui City-demonstration of High yield cultivation techniques of 100000 mu Kernel Apricot" jointly undertaken and implemented by Tianshui Fruit Tree Research Institute and various county horticultural departments has passed the appraisal of the achievements of the Provincial Department of Science and Technology. Experts believe that the project uses "four wasteland" to build a kernel apricot base, which not only saves cultivated land, but also plays an important role in reducing soil erosion, preventing wind and fixing sand. Its achievements have reached the advanced level of similar projects in China. Up to now, the city has built 20 mu of kernel apricot seed harvest orchard and established improved varieties.
