A Detailed Guide to the Latest Planting Methods for Sapphire Grapes
Sapphire grapes are also called Tears of the Moon, and they are a mid-season variety in grape cultivation. Sapphire grapes have plump, juicy, seedless flesh that is crisp and sweet with no residue, making them the finest among grapes. Their nutritional value is also at least ten times higher than that of ordinary grapes, and the market price generally stays at thirty to fifty yuan per jin, while they can also sell for the high price of one hundred and twenty yuan per jin. So how should sapphire grapes be planted? Are there any differences from ordinary grape planting? Let us take a look at their planting methods together below.
1. Planting Preparation
Sapphire has the characteristics of high yield and easy cultivation. It has strong adaptability to soil, and general soil can be used for planting, but soil rich in organic matter is best for planting. So first we need to prepare the land and raise ridges. Land preparation is divided into deep plowing of the whole orchard and digging trenches along the rows. During land preparation, sufficient organic fertilizer needs to be applied as base fertilizer, and the organic fertilizer should be mixed evenly with the topsoil.
2. Cultivation Methods
The best time to plant sapphire is in spring, and we can use direct-seeded seedlings and grafted seedlings. But if grafted seedlings are used, before planting the rootstock buds need to be removed and the binding film untied, and then planting can be carried out. When planting, it is generally done along the rows, and the distance between each plant is generally about seventy cm. After planting, a large amount of water needs to be poured, then soil should continue to be filled in, and finally a layer of straw should be spread over it and watered thoroughly, then a layer of plastic film can be covered.
3. Soil, Fertilizer and Water Management
After planting, in order to promote the growth of sapphire grape seedlings, we need to water about once every week. Each time we water, we need to apply an appropriate amount of compound fertilizer as a top dressing, and spray foliar fertilizer about once every half a month. Throughout the four seasons, we can spread a layer of grass in the field. After the withered grass decays, it will produce nitrogen, which will then be absorbed by the soil and used to promote the growth of the plants.
4. Trellis Building and Pruning
When the sapphire grape seedlings grow to about one m, we need to start building a trellis, and guide the grape seedlings onto the trellis so that they grow creeping along it. Next, the pruning technique for sapphire seedlings is also crucial. First, we need to cultivate two main vines, then promote the growth of side vines, which can increase the yield of sapphire. Second, we also need to carry out winter pruning so that after sprouting they produce large clusters, which is also what we often call the small dragon trunk pruning technique.
5. Flower and Fruit Management
Management during the flowering and fruiting period mainly consists of promoting flower buds, protecting flowers and fruits, and thinning flowers and fruits. In order to have more clusters and strong clusters and form plump flower buds, we need to apply heavy fertilizer and water before flowering, and reasonably regulate foliar fertilizer to promote the growth of reserve branches, while paying attention to the prevention and control of pests and diseases. Second, in order to protect flowers and fruits, we should balance fertilization, use micro-fertilizers in combination, and carry out artificial supplementary pollination and temperature regulation. During the flowering period, reasonably thin out flowers that are too densely opened and relatively weak. About twenty days after fruit set, carry out reasonable fruit thinning, and use bagging technology to prevent and control pests and diseases.
