The red grapes are big, the fruit is juicy and sweet. The improved economic benefits are summarized below in terms of the high-quality production and cultivation techniques of their solar greenhouses。
Pre-plant preparation. Digging canals at a distance of 1. 8 metres and with a width of 0. 8 metres, separate the excavated soil from the ground and leave it open for three days. At the time of filling, a ten centimetre-heavy wheat straw or maize straw was covered with 10 centimetres-heavy corroded soil, which was fully ploughed into the corroded soil, full decomposed farm fats and sands at a ratio of 1:1:1,1 centimetres, 40 centimetres thick, which was filled with 10 centimetre-heavy corroded soil, 2 kg of calcium phosphate and 10 centimetres thick of the ground per gutter surface, and the water was sank and planted, 15 centimetres tall and 80 centimetres wide. Some five days of pre-plant plaque cover, which increases the temperature of the earth. The seedlings were immersed in the water for 24 hours one day before the planting, and needed to be trimmed for their excessive length。
The plant is designed to dig up one detachment every 1. 2 metres, 300 grams of urea and 200 grams of ammonium phosphate. The depth of planting is based on 1 to 2 seedings of branches. When it is finished, the patches are broken, the sheeting sheeted, the film is 1 metre wide, and the surroundings are covered with the earth。
Fertilizer management fills the water immediately after planting, and it flows to the bottom. With it the seedlings shall be firm, and the buds shall grow green, and they shall be removed from them, and they shall be cleaned up. Persisting on moderate and rational application of nitrogen fertilizer to increase the proportion of potassium phosphate. From october until the fall of leaves, fertilizers are applied, mainly in fully decomposed organic fertilizers, and in a timely manner during the growing season. 3% zinc sulphate solution before pre-sprouts and 0. 3%-0. 5% urea and 0. 2%-0. 3% potassium phosphate solution during the growing season. Water is given flexibility based on soil, small climates in the greenhouses and plants。
Temperature control for unpacked, unscathed grape seedlings, normal growth of buds, planting, membrane, watering, three gradual warmings. Specific methods: to put down all the straw curtains, no light in the room, to close the vents and to hold the temperature at 10°c for the first five days; to pull one curtain at 15°c every three to five days for 5 days for 5 to 10 days; to pull one curtain at 20°c every one day for 10 to 15 days; to pull all the curtains at around 25°c for 15 days when the bud becomes green. The night temperature stabilized at more than 12°c and began to deface the film until mid-may, when it was completely removed。
The tree management, after planting, leaves a new sprouts for each of the sprouts, set up at 30 to 40 centimetres long, and removes the springing sprouts from the new sap. A new 80-centimetre length is provided by heart and by the retention of two dots at the top, and a 50-centimeter dot at the side, and two leaves at the top of one to two dots are repeated so that the main branch accumulates nutrients and fosters buds. Cuts the swabs on the top of the new floor in time for growth. After august, two blades were circumcised on the second section of the result branch, with a gap of 0. 5 to 1 cm. The result period is 10 to 15 leaf blades on the top of the ear, and 4 to 5 leaf blades on the second end of growth, as appropriate。
Flower fruit management, by the principle of one-hundred-and-one-two end branches, removes the bouquets from their nutrients, strangulates the ears, which tends to fall down the ladder and sting when they are crowded. • the timely removal of small particles, malformations, bruises and overtly compacted and pressing grains from the ears of the fruit, which retain 40 to 50, the ears of the medium and 80 and the ears of the large 80 to 100. A timely package of pellets after oscillation is sprayed with bordeaux on the ear, and a drenched bag for the drug. 20 days before harvest, remove the paper bags and flip the fruit ears。
The main diseases of the grapes are albinosis, anthrax, black pox, ashilosis, etc., which should be treated with medication。
The expert conducted a pilot study on the production of red-tied grapes, which yielded high-quality productivity benefits。
