I. Garden selection
Wine grape seedlings have strong adaptability to soil, but the most suitable for growth is rich in inorganic, loose and fertile, neutral sandy loam and loam.
The mountainous lands will be built on sunset slopes with a slope of no more than 25 degrees and terraces above 10 degrees.
Regardless of mountains and plains, we must have good irrigation and drainage conditions, and the dark water level should be less than 1 meter. Avoid low-lying, accumulating, and salt alkali. Height must be around 5 meters to build a garden.
Second, site planning and design
1. The direction of planting, and the type of wine grapes that stand on top of the land are good to the north and the south. The purpose of the mountain is to use the hedgerows for planting.
2. The distance between rows of rows of plants is 2.5 meters and the spacing between rows is 0.5-0.55 meters, and 500-530 plants per mu.
3. The roads and protective forests have a large area of ​​vineyards. The main road is established. The width is 6 to 7 meters and the whole park is integrated. Community building branch, 3 meters wide. Field management road, 2 meters wide. Design to facilitate fieldwork. The grape seedling gardens are small or scattered, with only fieldwork paths. The protective forest in the vineyard area determines poplar, eucalyptus, and amorpha, etc.
4. Drainage and drainage channels The planning of drainage and irrigation in vineyards should be dispersed with the road. On the side of the journey, a three-stage water injection system for watering the main, branch and furrow (planting ditch) is provided. The main methods are canal irrigation, drip irrigation, pipe irrigation and other methods. Digging trenches on the other side of the road (main road), especially in locations with high groundwater level and low lying, the drainage system is not necessarily sluggish, the plains are best connected with the river, and the mountain is connected with the pond or reservoir for drought. When used for watering.
5. Houses and workshops are established in the center of the vineyards and facilitate the establishment of transportation facilities for the establishment of houses and workplaces for the benefit of homework.
Three, pre-planting site preparation
1. Site preparation and soil improvement Before planting, use a rotary cultivator to deepen the site, remove debris, and spread the land. Deep plowing in the mountains, deeper than 60 cm of live soil, organic fertilizer added; plains to build a garden gently slope or flat ground. Pay attention to soil and water conservation and soil improvement. The sandy land must be mixed with clay, loam, and organic fertilizer. The clay soil must be blended with sandy soil and organic fertilizer to improve the soil.
2, digging planting ditch in accordance with the line to dig planting ditch, digging one every 2.5 meters. The depth and width of the ditch should reach 60 to 100 cm. When digging trenches, topsoil and raw soil are separated and dispersed.
Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
