Peach pacifier is commonly used in peach area to control the growth of new shoots, resulting in many side effects. If the type is small, the tree vigor is weak and the result is short life. We have promoted a new type of foliar fertilizer, PBO, to replace paclobutrazol in Yangshan, Wuxi, and achieved good results.
First, the use of effects
(1) No toxic side effects. PBO can control the growth of new shoots, promote fruit enlargement, no residue, and meet the green production requirements.
(2) High quality, output and efficiency. Compared to paclobutrazol, the quality of PBO in peaches is higher than that of paclobutrazol in 4 years. The quality of PBO is higher than that of paclobutrazol, and the yield is a step higher. The fruit type is large and uniform, with high sweetness, easy peeling, and fruit solute, less fiber, and fragrance. Thick, white and red skin color, quality and superior.
(3) The result is long life. PBO's tree vigour is robust, and it is late in senescence. It is 3 years more fruit than the garden with paclobutrazol. (4) Stable production and high output. PBO's tree has a high fruit setting rate and prevents dark frosts and cold currents, ensuring high yields year after year. (5) Full flower buds and labor-saving fertilizers. PBO's tree has no branches and erect branches. The whole tree is basically a medium-long fruit branch. It is airy and light-transmitting, and it produces high quality flower buds. It also saves more than three trimming hours and reduces nutrient loss.
Second, the use of methods and methods
(1) The first time. In the 15 to 20 days before flowering, that is, March 5 to 10 spray 100 times PBO 100 times, when the sap has flowed, bark and bud eye cells can absorb PBO, it requires full spraying of the branch and trunk, Spray should be meticulous and thoughtful. After use, the new shoots are strong and strong, with large and thick leaves.
(2) The second time. When the new shoot is up to 10 centimeters long (April 15th to 20th), it sprays PBO liquid one time, strong in the tree vigor is sprayed 100 to 150 times, and the tree vigor is sprayed 70 to 100 times. The purpose is to control. The new shoot is long and promotes fruit enlargement.
(3) The third time. From May 10 to May 20, when the tree vigor is strong and the shoot length is about 30 centimeters long, the diluted concentration is the same as the second time. For strong trees, the new shoots are still prosperous for 4 to 5 days after spraying. Spray 1 time, so that the entire tree maintained in the best leaf area and photosynthetic utilization state, fruit enlargement fast, easy to drop fruit, high yield, less perforation.
(4) The fourth time. Spray 100-120 times of PBO in early June to promote fruit enlargement and increase sugar content.
(5) The fifth time. Immediately after the end of harvest, chase post-harvest fertilizer, and irrigation, to supplement the loss of tree nutrients, in order to prevent the growth of new shoots, immediately spray PBO, strong tree spray 70 times fluid plus 0.3% urea, medium strength tree spray 100 ~ 150 Adding 0.3% urea solution to the liquid will help flower bud differentiation and lay a foundation for high quality and high yield next year.
Third, pay attention to matters
Different climate and management levels in different regions should be applied flexibly according to tree vigor. Water and fertilizer should be strengthened for weak trees. Spraying 300 times of PBO three times per year can promote growth, and tree vigor can be sprayed after spraying 150 times. After the use of drugs to strengthen the comprehensive management of fertilizer and water, in the fall to apply high-quality basal fertilizer, in the expansion phase of timely irrigation and fertilizer. PBO can be mixed with pesticides and urea (except for lime sulfur).
