Planting techniques of Jingya Grape

Jingya grape is a new grape variety bred by European and American hybridization. it has a sour and sweet taste and is deeply loved by people. at present, it is cultivated in Beijing, Zhejiang and other places in China. What are the planting techniques of Jingya grape?

1. Site selection and construction of sheds

Choose a piece of land with convenient transportation, adequate water and pollution-free surroundings, and try to stay away from the urban area. Then build a greenhouse with a width of 1.5 meters, a ditch width of 0.6 meters and a length of about 40 meters according to the Northern and Southern dynasties, and build an arched skeleton, iron wire, plastic film, and finally sprinkler equipment.

2. Seedling planting

Select some healthy and good seedlings, according to the row spacing of 1.7 meters, plant spacing of 0.7 meters to the soil, and cover the soil to water, generally planting about 400 plants per mu.

3. Management technology after planting.

The main results are as follows: (1) coring: the growth characteristics of Jingya grape before flowering are similar to those of Jufeng, and the drop of flowers and fruits is more serious, so it is necessary to leave 5 leaves and 7 leaves before the ear 3-5 days before flowering in order to improve the fruit setting rate.

(2) spraying: the phenomenon of grain size of Jingya grape sprayed with borax at flowering stage is more serious, and borax can be sprayed twice at flowering stage, and the effect is better. The grape expanding agent soaked after anthesis can improve the fruit setting rate and solve the phenomenon of large and small grains. The soaking time is 7-10 days after anthesis. If the gibberellin of 50PPm is soaked once before flowering, seedless Jingya fruit can be produced.

(3) ear trimming and shaping: remove the accessory spikelet and the first and second spikelets, and remove the lower part of the inflorescence. The finished ear is nearly cylindrical, neat and beautiful, resistant to transportation.

(4) Fertilizer and water management: pre-anthesis management is the same as other varieties, water and fertilizer should be applied earlier than other varieties, especially before the young fruit is enlarged. Pay attention to the control of nitrogen fertilizer in the later stage.

4. Timely harvest

Jingya grape harvest early acidity, the market is not easy to accept, late harvest fruit is easy to wrinkle. The best harvest time is within a week after the fruit color changes to purple and black.

Generally speaking, Jingya grapes are well cultivated, as long as they set up a shed, select seedlings, plant them in the soil at an appropriate distance, and finally do a good job of fertilizing and watering, pruning, picking flowers, and so on.
