How to plant red raisin seeds

Red grapes are also known as "Red Earth" grapes. It was introduced into China in 1987 and is mainly planted in Shaanxi, Xinjiang, Jiangsu and other places. This grape variety has good quality, high yield and good taste. So, how to plant red raisin seeds?

1. How to plant red raisin seeds

Potted seeds have strong adaptability to soil, and fertile sandy loam is the most suitable. Then dry the ripe raisin seeds, sow them directly into the prepared basin soil, cover the soil with 50mm, and pour the right amount of water. When selecting a basin, it is best to choose a ceramic basin with a caliber of 35 to 50 cm and good permeability and air permeability. It is best to water it in the later stage, and it can sprout in less than half a month.

2. Cultivation techniques

1. Reasonable establishment of the garden

The main results are as follows: (1) the pollution-free cultivation area of Hongti grape should have no pollution of atmosphere and water resources, and have better water and gas environment.

(2) the topography is higher, preferably sloping land, sunny, transparent, no larger buildings around, the soil is dry, and has better irrigation conditions.

(3) in sandy loam, there are no harmful heavy metals in the soil, such as Pb (2 +), Hg (2 +) and so on, and the groundwater level is lower (below 10m).

(4) the ear of red grape can be divided into two types: sparse type and dense squeeze type. it is necessary to choose sparse type so that the gap between fruit grains is large and the chance of disease is reduced.

(5) the density should be small, in order to improve the ventilation and light transmittance and reduce the pathogenic factors, the plant spacing is 1.5m and the row spacing is 6m.

2. Fertilizer and water management

It is necessary to adhere to the principles of fertilizer and water management that large fertilizer is suitable for water, rational application of nitrogen, and increasing the ratio of phosphorus to potassium.

It is important to fertilize and water four times a year, and it is important to water and fertilize when sprouting. Fertilizing and watering should be carried out in the grape grain growth period and coloring period. Fertilize and water before freezing. Frozen fertilizer is fertilized and watered in autumn, and this fertilization and watering determines the growth of grapes in the second year.
