Grape sparse-planting ridge-planting early-maturing cultivation method

Abstract

The invention belongs to the technical field of plant cultivation, and discloses a grape sparse-planting ridge-planting early-maturing cultivation method. The method comprises the following steps thatfield planting is carried out on December to February 10th, and seedling grafting in the same year is performed with the planting spacing of 2*5m, wherein the field planting ridges are trapezoidal, the lower bottoms of the field planting ridges are 1.4-1.6 m, the upper bottoms are 1.2-1.4 m, and the heights are 50-60 cm; the field planting soil is mixed soil of organic fertilizer, organic matterand soil according to a certain ratio; standardized frames such as T-shaped frames and H-shaped frames and the like are arranged on branches and tendrils; and flower and fruit management directly adopts an innovative closed flower pollination fruiting technology. A series of researches are carried out by developing novel healthy cultivation technologies such as extremely early maturing and early maturing varieties suitable for facility early maturing, direct soil formula improvement, simplified branch and tendril management and closed flower pollination fruit setting, the soil quality is continuously improved, healthy trees are cultivated, the frame shape is optimized and simplified, manual operation is simplified, and therefore the purposes of saving labor and cost, improving the qualityand improving the efficiency are achieved. The healthy and sustainable development of the facility grape industry in the corresponding city is promoted.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for promoting early cultivation of grapes by sparse planting and ridge cultivation. Background technique [0002] At present, grape cultivation in Wenling City began in the early 1980s, and gradually developed into greenhouse cultivation in the 1990s. By 2019, the city’s grape cultivation area exceeded 60,000 mu, with an output of 67,900 tons and an output value of more than 574 million yuan, accounting for More than 60% of the grapes have become the main production area of ​​the grape industry belt in the eastern coastal area of ​​Zhejiang Province among the three industrial belts in Zhejiang Province. In order to avoid the harm of typhoon, 100% of the grapes in our city are cultivated in greenhouses for heat preservation. The listing period lasts from the end of April to the beginning of July, of which 70% are concentrated in the market from May t...

AI Technical Summary

Problems solved by technology

[0005] Through the above analysis, the existing problems and defects of the prior art are: (1) the leaf curtain is planar, and the tree shape is chaotic, not only the management is laborious, but also the shelf surface is closed, the ventilation and light transmission are poor, the pests and diseases occur heavily, and even the leaves fall prematurely , affecting tree nutrient accumulation

[0006] (2) High groundwater level in the garden, flat footed furrows, long-term human trampling lead to soil bonding, coupled with improper use of fertilizers (partial application of chemical fertilizers, insufficient application of organic fertilizers), obvious soil acidification, and salt accumulation on the soil surface, soil secondary Serious salinization

[0007] (3) The flowering period of early cultivation is from February to March, which is the season with frequent low temperature and rainy days in the south, which often leads to poor pollination and fertilization, resulting in more large and small fruits, unisexual fruits, and irregular fruit ears

The current conventional flower and fruit preservation technology still cannot completely overcome the influence of bad weather

[0008] (4) The existing facility grape early cultivation technology, due to factors such as frame shape, fruit treatment methods, winter pruning, branch and vine management, flower and fruit management, etc., requires a lot of labor, and the artificial production cost is relatively high, which directly affects the improvement of planting benefits

(4) The new technology must be mastered accurately. For example, if the first time of flower and fruit treatment is too early, it will cause the flower spikes to be too long, which will be easily affected by the weather, the fruit grains will be uneven, and the shells will not be completely shelled; If there are too many fruits, the flower spikes are too short, and the fruit thinning time is prolonged, and incomplete shelling will also occur.
