A course on the latest cultivation techniques and methods of raisins

Raisins are a kind of fruit that tastes very good. This kind of fruit has no seeds and belongs to a kind of grapes. It tastes very crisp. Everyone likes to eat raisins, which are also called American grapes. Its hometown came from California in the United States and was later introduced into China. Raisins are not cheap in the market, and they are very expensive, so how to grow raisins? Next, Shuai Shuai will introduce you!

1. The growing environment in which raisins are suitable for planting.

1. If you want to grow high-quality raisins, you must choose a suitable environment. Qingdao and Fuzhou are the first places to introduce raisins in China, which shows that most parts of China can be planted, and the environment is suitable for the growth of raisins. We can choose to plant on hills and flat land, and the soil has good air permeability and drainage, and the best soil is sandy.

2. During the sprouting and flowering period, if the humidity in the soil and air is too high and the moisture content is too high, it is easy to catch the disease, so choose a moderately dry and wet ventilation zone, when the fruit is growing, we need to increase moisture. When the fruit is ripe, it is necessary to keep the environment low and wet. The vine is afraid of the wind, especially in windy weather, it is easy to make the scaffold collapse. Therefore, we should try to choose places to stay away from the wind. For light, raisins do not like to grow in a shady environment. Without enough light, the vines will grow very thin and thin, affecting the photosynthesis of the leaves. When the sun is big, we should pay attention to shading, because the fruit can not be strongly illuminated during the growing period, otherwise sunburn will occur.

2. Key points of planting and cultivation of raisins.

1. Cultivation time

Generally choose to be better in spring and autumn, the survival rate of planting in these two seasons is higher than other seasons, and the best time is from early February to late February. During cultivation, the density should be determined according to the shaping method, usually the distance between each plant is 1 m × 3 m, and the base fertilizer should be fully applied before planting.

2. Fertilizer and water management

At the initial stage of cultivation, the water should be fully irrigated to make the soil moist enough, and if there is a drought in the growing period, it should be watered in time, and if there is stagnant water in the garden, the stagnant water should not be discharged for too long, otherwise there will be mildew roots. until the end of October to the first ten days of November, the base fertilizer should be fully applied, and the number of fertilization is about 8 times a year.

3. Pest control

Before the plant sprouts, spray the mixture of stone sulfur mixture 3-5 degrees and pentachlorophenol sodium 200-300 times to kill the pathogen. After the first leaf unfolds, it should be sprayed every 10 days. Once a live worm is found, it can be wiped off with a dishcloth.

The above is the planting and cultivation technology of raisins. After the fruit is ripe, the ripe ear is harvested, one ear is ripe, and the rule of harvest in batches is adopted. If you are planting in a large area, you must choose the planting site in advance, which is very important, and whether the soil meets the requirements and whether the fertility is enough need to be considered in advance, so that it can be foolproof.
