Method of guaranteeing germination uniformity of overlong main stems of grape in northern buried culture area

Abstract

The invention relates to the field of fruit tree cultivation, in particular to a method of guaranteeing germination uniformity of overlong main stems of grape in a northern buried culture area. The method comprises the following steps: from safe overwintering to an expanding period, smoothly placing grape branches and tendrils which are unearthed on the ground in a planting line; and directly supplementing a small amount of water to the branches and tendrils for many times at a high frequency till being erected close to the germination stage or in the initial germination stage. By directly supplementing a small amount of water to the branches and tendrils for many times at a high frequency, front eyes in the overlong main stems are prevented from air-dried by frequent dry and cold monsoonin spring, so that the germination rate and the uniformity of extended tips are improved. By adopting the method, the main stems are unearthed and erected according to a germination process of a conventional year or indicative tree spring germination without worrying about early time or later time. By fully executing the automatic or semi-automatic advantage of high standard modern grapery irrigation equipment, the water utilization ratio is improved and the labor cost is lowered. Moreover, the method does not increase the water content of soil while supplementing water of the grape branches and tendrils, so that ground temperature rise again in spring is facilitated.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a method for ensuring the germination uniformity of super-long main vines of grapes in the northern soil-buried cultivation area. Background technique [0002] In most of the northern regions where grapes are buried in soil, due to the dry and cold weather conditions in winter and spring, the heat preservation and moisture retention of grape branches and vines are particularly important. The cultivation habit of burying grape branches and vines in the soil for overwintering has been used for thousands of years. Similarly, due to the dry and cold climate in winter and spring, the length of the main vines in the buried cultivation area is only tens of centimeters to 1 meter. Germination barriers limit the rapid formation of vines, and the effective utilization rate of annual growth is also low. However, due to the vine characteristics of grapes and the concentrate...

Problems solved by technology

[0004] This pre-emergence management method of grape vines in the buried area has the following defects: (1) The unearthed time is difficult to grasp, because the temperature fluctuates greatly in spring in northern my country, it is not suitable to accurately judge the time of moderately late unearthed or staged unearthed, and often occurs If the unearthed time is early or late, the bud eyes will swell later, and the damage will be greater if it is knocked off in the follow-up operation, and the branches and tendrils will lose water seriously, which will affect the stability of the germination rate.

(2) Water immediately after unearthed, and most of the water has been added to the soil. During this period, due to the limited water loss during pre-winter irrigation and winter freezing (especially the soil in the rhizosphere), the soil moisture content will be excessively increased. For spring The unfavorable rise in ground temperature will delay the germination period. At the same time, when the wind and cold effect is obvious in spring, the water in the branches and vines still cannot be replenished in time, and the germination rate is difficult to guarantee.
