In the past two years, the phenomenon of falling fruit and fruit of artificially cultivated gardenia is very common. In 2006, the fruit collection rate of gardenia in some major producing areas reached 20% to 40%, and some of them reached more than 50%, which seriously affected the yield and economic efficiency of gardenia. The main causes of falling fruit are: lack of nutrition; imbalance between vegetative growth and reproductive growth; lack of nutrient supply during flower bud differentiation; incomplete pollination during flowering; For this reason, the following measures must be taken in production.
Scientific Fertilization: In the early growth stage of wolfberry fruit, nitrogen fertilizer is the main application, which accelerates vegetative growth, enhances photosynthesis, and accumulates more organic matter. When entering the reproductive growth period, chlorine fertilizer should be controlled, and phosphorus and potassium fertilizers should be added to promote more flowering results. Such as in the spring after germination, urea per acre 3 to 4 kg, to promote the longevity; after flowering, apply ammonium bicarbonate 4 to 5 kg to facilitate fruit setting; after the fall of autumn after the application of fertilizer, application of 6 kg of urea, adding humans and livestock Manure water 100 kilograms, digging a hole next to the plant to apply water, cover the soil; after fruit picking in winter, re-apply wax fertilizer, apply fertilizer or compost with superphosphate, cake fertilizer mixture of 300 kg of mixed fertilizer, in Plants are applied with a circular gutter next to the plant and soil is applied after the planting to facilitate safe wintering and restoration of tree vigor.
Spraying auxin: Spray 0.15% borax at the flowering stage of medlar; spray 3/4 of the flower and spray with a concentration of 510-6 gibberellin (GA) or 810-6 to 10-5. Concentration of 2,4-D plus 0.3% urea, 0.2% potassium dihydrogen phosphate mixture, spray once every 10 to 15 days, and even spray twice, can promote the growth of wolfberry fruit, accelerate cell proliferation, reduce fruit stem separation The formation of this can increase the rate of fruit set.
Reasonable pruning: After planting, pay attention to eradicate the sprouting of the lower trunk, and make the scorpion tree a natural open shape with the crown open. In the first year after planting, the main stem was removed from the ground within 20 cm of the bud, and was used as a fixed height. When the summer shoots grow 18 to 20 centimeters in length, 3 to 4 different growth branches are selected from the middle shoots and cultured to become the main branch. In the summer of the 2nd year, 3 to 4 strong branches were selected among the three branches of the main branch, and they were cultured as sub-branches, growing in different directions and extending the shoot in turn. Later, the side branches will be released on the secondary branch. In the third year, it will enter the result period. Through reasonable pruning, the canopy outer circle will be empty, branches will be sparse, ventilation and light transmission, and the balance between growth, development, branching, flowering, and results will be adjusted, and nutrients will be reduced. The consumption increases the result area.
