The porcelains are four-fold well-established varieties, with dark black purple and blue black colours, velvet powder, fruit round and egg round, even sizes of fruit grains, almost identical colours and a certain aroma。
Magnificent grapes are four-fold sophisticated varieties, colours are dark, purple and blue and black, skin-fruit powder, fruit round and egg round, equally large in size and colour, with a certain fragrance, high fragrance, fresh, non-smuggling, taste-friendly, soft, juicy, easy to eat, easy to separate from meat, meat and seeds, compatible with the concept of quality fruit consumption, with a vast market space and an excellent economic crop. However, giant grapes are characterized by poor stability of the sitting fruit, and are prone to flowering fruit during the planting of giant grapes, which are sensitive to fertilizer, moisture and cut strength and whose cultivation is not easily controlled。
The agricultural technology station, li mya fong, of the loang street office in fouan, fujian province, summarized the techniques used in the area to grow grapes, including:
Park selection
Large-peak grapes require a good ecological environment, with good isolation conditions, easy drainage, relatively high terrain and platforms, ventilation towards the sun, soil fertility, high organic content, suitable for gravel and sandy border soil at ph 6. 5-7
The seedlings choose and plant
The choice of suitable, highly resistant, virus-free, high-quality, high-quality grape varieties is based on a full understanding of local climatic conditions. The planting time of the seedlings is appropriate for february-march of each year, and the density of the seedlings is appropriate at a distance of 2. 5 metres and 1. 8 metres, with 148 plants per 667 square metres。
Fertilizing and watering
Cultivation should focus on the control of fertilizers, which should be applied in accordance with the principle of hard pursuit and small number of times. The winter base fat is dominated by decomposed farm fertilizer, supported by fertilizers, common acre application of 7-8 tons of decomposed organic fertilizer, potassium chloride or potassium sulphate (preferably potassium sulphate) of 10-20 kg, and calcium perphosphate or phosphorus of 50 kg of fertilizers, with no need to add velocity chlorine fertilizer to the application of base fertilizer. Before the spring bloom, do not try to fatten the water without excessive drought, in order to avoid the pre-growing and adverse effects. Following the flowering, the promotion of branch enrichment increases the rate of lumbering, and the application of diammonium phosphate or high phosphorous compound fertilizers can be followed before the water is poured. Precautions are fast and long-lived, with application of ammonium phosphate or decomposed chicken and goat dung, etc., and leaf-faced fats can be sprayed to boost the expansion of the crop, water can be fertilized after application, summer fruits will mature, quick-effect fertilizers dominated by phosphorus fat can be applied, high phosphorus fat can be sprayed on the leaves to promote the maturity of the branch and the colour of the fruit. The fall fruit harvest can be based on a ratio of about 3,000-5,000 kg per 666. 7 m2 of decomposed organic fertilizer, with appropriate amounts of calcium perphosphate and compound fertilizer。
Integrative trim
The oscillation of giant prairies shall be formed in the form of a torn tree, divided into summer and winter trim. In the summer, the curvature must first be grafted, the grafted, the sprouts must be removed, the sprouts must be sprouted, the lumber sprouts must be seen, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, the raisins must be removed, and the raising must be lengthened, and the blades must be lengthened by a length of 15 centimetres, so as to ensure that the rais is radiant, so that the fruit rate is increased。
In winter, shearing should be done after the leaves fall from the grapes, before they flow, and after determining the length of the branches, mainly with mid-long mats, with as little as possible trimmed, with sprouts in the vicinity of the cranberry heart, with six to eight result branches within each square metre of the surface, and with care to stagger. And in accordance with the principle of shape-forming trees, the trimmed chickens are drawn to the shelf in time for the coming year。
