Study On The Technology Of Abundant Grape Cultivation In Spring Festival

In order to shorten the reporting period of protected grape and improve the cultural benefit of protected grape,using the habit of grape bearing many times,10-7grape strain was selected to plant the grafted seedling in the first ten days of March in the technique of delayed cultivation of protected grape.20 cm × 2 m plant row spacing and stand were used as experimental materials to study the effects of different node cuttings on plant growth,and the effects of different cutting stages on plant flower formation,growth,development and yield.The results show that:1.On June 1,different node truncation treatments of 10-7 grape lines were carried out to retain 2 knots,5 knots and 8 knots,respectively.It was found by comparison that the growth of new shoots in the treatment of retaining 8 knots was the largest,which was significantly larger than that of the other two treatments.The growth of new shoots after truncation was as follows: retaining 8 knots > retaining 5knots > retaining 2 knots.2.After planting and germination of 10-7 grape strain,the plant was cut off in different period.The 10-7 grape strain was planted in early March and began to sprout in late March.On June 1,June 28 and July 26,respectively,when the fruit of10-7 grape was on the market for the Spring Festival,the early flowering period of the plant should be in late September,in order to prevent excessive lignification of the mother branch.Therefore,on the basis of the plants that were cut off on June 1,the second truncation was carried out on August 15.The growth of new shoots after truncation can be shown as follows: short cut on June 28 > second retraction on August 15 > 7 Short cut on June 26 > short cut on June 1.The results showed that the number of spikes after cutting was as follows: June 28,short cut,August 15,second retraction,July 26,short cut,June 1,short cut.The results showed that the ear quality after cutting was as follows: June 28,short cut,August 15,second retraction,July 26,short cut,June 1,short cut.3.It was found in the experiment that the lignification degree of the plantstreated with short cut on July 26 was too high,which affected the flowering of the plants,and the plant growth and heading number of the cut treatment on June 28 and the second retraction treatment on August 15 were found to be too high.There was no significant difference in fruit quality,but the fruit ripening period of secondary retraction treatment on August 15 was about the middle of January,which was closer to the Spring Festival.
