1. The reasonable dense planting of Jingya grape grows weaker than Kyoho, so the planting density is slightly larger than Kyoho, and the average row spacing is 1.7 to 2 meters, the plant spacing is 0.7 to 1 meter, and 400 acres are planted.
2. Before harvesting, the focus on the growth characteristics of the Jingya grape is similar to that of Kyoho; the flower drop is more serious, so it is necessary to leave 5 to 7 leaves in front of the ear for 3 to 5 days before flowering to increase the fruit setting rate.
3. The spraying of borax in the flowering period of Jingya grapevine is quite serious, and the borax can be sprayed 1-2 times during the flowering period, and the effect is good.
4. After flowering, grape dilating agent impregnating grape enlargement agent is very obvious to increase the fruit setting rate and solve the problem of size and size. Dipping time is 7-10 days after flowering. If a 50-ppm gibberellin is also immersed before flowering, a seedless kernel can be produced.
5. The control of output and yield is the basis of good quality and the guarantee of economic benefits. The ideal output is about 2000 kg per mu.
6. Reclamation repair removes the spikelets and the first and second spikelets and removes one-fifth of the inflorescence in the lower part. The finished ear is nearly cylindrical, neat and beautiful, and resistant to transportation.
7. Management of fertilizer and water management before flowering is the same as other varieties. Water and fertilizer during flowering should be applied earlier than other varieties, and water and fertilizer should be promoted before the expansion of young fruit. Pay attention to controlling nitrogen fertilizer in the later stage.
8. Timely picking of the Jingya grape harvested earlier had a large acidity, the market was not easy to accept, and the late harvest of the fruit was easy to wrinkle. The best harvest period is within one week after the fruit becomes dark purple.
