Early cultivation techniques of grape in Shouguang solar greenhouse

Rose honey

Generally, the grapes begin to heat up and sprout before or near the end of natural dormancy. Through the heating and heat preservation function of the solar greenhouse to realize the early listing of grapes, the general maturity period is 60-90 days earlier than that on land. The varieties recommended by our company are rose honey (red variety) and yellow mi (green variety), which can be listed in April. The output is controlled at about 5000 jin, the price is about 10 yuan, and the benefit is very objective.

The solar greenhouse belongs to the industry with high capital investment, high labor intensity and high output benefit, so that the cultivation of grape must make full use of the light and heat resources of the greenhouse to maximize the comprehensive benefit. The greenhouse grape cultivation management experience of Shouguang grape growers for more than 20 years is summarized as follows:

The main results are as follows: 1. The general trend of the row spacing of grape cultivated in the cultivation model is to change the number of sparse plants to close planting, and the grapes are cultivated and pruned by dense planting Dulong stem, the plant spacing is 50cm, the row spacing is 90cm, and there are about 1500 grape plants per mu. The advantage of this cultivation model is to make full use of the light and heat resources of the solar greenhouse to maximize input and output. It will be planted on May Day this year and will sell grapes around May Day next year. 1500 plants were planted per mu, each plant cultivated a strong fruiting mother vine, the fruit per plant was about 3-4 jin, and the yield per mu was controlled at about 5000 jin, among which the yield of red varieties such as Zaosheng Gaomo was between 4000-5000 jin per mu, and that of green varieties such as Qingti was between 6000-7000 jin.

2. Preparation before planting and standardized management after planting the grape root system is deep and widely distributed, so it is necessary to turn the soil deeply and apply sufficient bottom fertilizer before planting. The fertilization standard per mu is about 8 cubic meters of mature farm manure and 100 kilograms of calcium superphosphate. Do not use quick-acting chemical fertilizer. In recent years, grape growers in Shouguang directly apply organic fertilizer in actual production, and then use rotary tiller to turn the whole greenhouse deep on both sides. Stir the fertilizer and soil evenly.

Post-planting management: if you want to put into production in the second year, you must be fat and water. In addition to flooding immediately after planting, the seedlings must be watered again before germination, and the nutrition cup seedlings depend on the humidity. When the new vine grows to 20 centimeters, it is watered every 15 days or so until early August, during which the next heavy rain can be watered less, but light rain is not a substitute for watering. Starting from 20 cm of new shoots, fertilizer must be applied before each watering or heavy rain, because digital technology requires planting in the first year and a bumper harvest in the second year, so it should not only promote rapid growth, but also promote the formation of flower buds, so each fertilization should be combined with nitrogen, phosphorus and potassium, and a shallow ditch should be opened with a high-quality quick-acting compound fertilizer of 10-15 kg / mu for a total of 7-8 times.

3. Flower and fruit management technology

(1) promoting flower buds: according to digital management technology, grape planting enters the prosperous period one month after planting, the first heart is picked at the height of 50cm, the second is at the third leaf of the new shoot, the third is at the second leaf of the new shoot after the last one, and the fourth is at the second leaf of the new shoot. After four times of coring, the vast majority of grapes can enter a high yield state.

(2) Flower and fruit thinning: the yield of each plant is determined according to about 3 jin, and the number of ears left is determined according to the ear weight of the variety. Seven days before flowering, the ear was thinned, and after the ear number was fixed, the ear tip of the varieties with different florescence on the same ear was cut off. The small fruit will never grow up, so it should be removed in time. Varieties with high fruit setting rate should also be thinned to avoid overcrowding.
