Is it better to brew beer barley or wheat? Key points of high-yield cultivation techniques of high-quality beer barley

Beer is the oldest alcoholic beverage in mankind and the third most consumed beverage in the world after water and tea. Beer was introduced into China at the beginning of the 20th century and is a foreign kind of wine. So is it better to brew beer barley or wheat? What are the key points of high-yield cultivation techniques for high-quality beer barley?

Is it better to brew beer barley or wheat?

When it comes to taste, it should be that barley beer tastes better. Barley has the effects of tonifying qi, broadening and nourishing food, helping digestion, calming stomach and relieving thirst, eliminating thirst and heat, and so on. High-grade beer is almost all made of barley.

However, in terms of nutrition, wheat beer has higher nutritional value. Wheat is rich in starch, more protein, a small amount of fat, a variety of mineral elements and B vitamins. Wheat beer is cheap and tastes a little bad!

Knowledge expansion:

General beer is made from barley malt as the main raw material, rice as starch auxiliary material, and hops, after liquid gelatinization and saccharification, and then liquid fermentation. Its alcohol content is low, contains carbon dioxide, rich in nutrition. It contains a variety of amino acids, vitamins, low molecular sugars, inorganic salts and various enzymes. These nutrients are easily absorbed and used by the human body.

Wheat beer-A beer brewed by upper fermentation or lower fermentation using wheat malt as the main raw material (accounting for more than 40% of the total raw material). "Wheat beer" is a very distinctive and attractive product in the type and type of beer, mainly produced in southern Germany, Austria and Belgium, using "upper fermentation", with raw materials of barley malt and more than 50% of wheat malt, hops, yeast and water. " Wheat Beer also has another name, White Beer, which comes from Weissbier in German and WhiteBeer in English. The most famous representative of "White Beer" is Berlin White Beer, which is produced in Berlin area.

Attached: key points of high-yield cultivation techniques of high-quality beer barley

First, actively promote improved varieties of high-quality beer barley and carry out rational distribution

The varieties with high yield, high quality, cold tolerance, early maturity and disease resistance suitable for local cultivation were selected: "S500", "83055", "83023", "Rudong 7" and "Xiumai 3". And carry on the reasonable layout according to the local conditions. "S500" and "Xiumai 3" with high quality and high yield should be vigorously promoted in Shaxi and Jinhuaba area. Yangzen, Shanglan and Madeng Town, which are relatively cold, should promote varieties such as "83055", "83023", "Rudong 7" and "Xiumai 3".

Second, strict seed treatment

The high-quality seeds of excellent varieties should be fully dried and cleaned before sowing, so as to improve the seed germination power, and mix the seeds with "trimethoprim" at 3/1000 of the seed weight to prevent the spread and harm of seed-borne diseases.

Third, grab the season and sow seeds at the right time

According to the production experience, the best sowing time in the main push area of beer barley is from late October to early November. Relatively cool mountain areas and wheat areas can be appropriately advanced to mid-or late October to seize the rainy season is not over, good soil moisture favorable opportunity to rush to sow. Sowing in this sowing date can make barley in favorable light and temperature conditions at each growth stage, with strong growth, full ear, large ear, many grains, grain weight and high yield. Otherwise, if sowing too early, it will be easily harmed by low temperature and frost, resulting in large yield loss; if sowing too late, the annual growth will be insufficient, the accumulation of nutrients will be less, the population will be too small, the stress resistance will be poor, the ear will be small, the grain will be few, and the mature period will be delayed.

IV. fine farming and standardized planting

It is necessary to grasp the suitable period of soil ploughing and leveling the land in time, carry out intensive cultivation, draw lines to open soil moisture, strive to achieve flat soil moisture, fine soil, flat ditch and flat bottom, ensure smooth drainage and irrigation, and create good soil conditions for barley to balance soil, fertilizer, air and heat, ensure that seedlings are uniform, uniform and strong, promote root growth, and lay the foundation for strong seedlings, strong plants, and enhanced stress resistance. General planting specifications: seven feet of moisture, six feet of soil moisture, strip, on-demand.

V. Scientific fertilization and economical use of water

Increase the application of base fertilizer and nitrogen, phosphorus and potassium fertilizer. It is required to apply 1000 kilograms of high quality farm manure, 25 kilograms of phosphate fertilizer (common calcium) and 10 kilograms of potash fertilizer per mu, 5 kilograms of urea for seed fertilizer, 810 kilograms of urea for tillering fertilizer according to seedling conditions, and 1520 kilograms of urea for jointing fertilizer per mu. Combined with the growth process, five water such as "emergence, tillering, jointing, heading and filling" should be well irrigated to promote complete, uniform, strong and strong seedlings, control vigorous growth, strong stalks and strong ears in the middle stage, keep beautiful and healthy in the later stage, and prevent premature senility or greedy green late maturity.

VI. Rational close planting to promote the coordinated development of groups and individuals

The number of grains per spike of beer barley is small, so it is necessary to win with more spikes, and the starting point of the population is higher. The suitable sowing rate should be determined according to the 1000-grain weight, soil preparation quality and fertility of barley varieties. Generally, the sowing rate of "S500" and "Xiumai 3" should be 25 kg per mu. "Rudong No. 7", "83055", "83203", with 25Muth30kg is suitable. The soil of individual fields is too sticky and heavy, and the sowing rate can be increased appropriately if the soil preparation quality is poor. The basic seedling should be about 25-300000 seedlings and the effective panicle should be 70-800000 ears to ensure the coordinated development of population and individual.

VII. Strengthen the prevention and control of diseases, insects and weeds

The existing excellent varieties of beer barley have strong disease resistance and generally have less disease, but the whole growth period should be checked frequently and aphid control should be done in time. Control index: the incidence of aphids is 15%, 20%, and when the number of aphids per plant is more than 5, spray with 40% dimethoate 800 murine 1000 times solution. Weeds: using the herbicide "Green Malone" 400g / mu, the weeds are in an one-leaf and one-heart period after sowing and are sprayed with water in the whole field. After barley closure, the damage of weeds is less in the case of large population. if a small amount of weeds occur, artificial weeding can be used to enhance ventilation and light in the field, so as to reduce the loss of diseases, pests and weeds to a minimum.

8. Timely harvest, high yield and high quality

When beer barley was harvested from the end of wax ripening to the full ripening stage, the grain appearance quality was good, the color was bright, the flavor was clear, and the brewing quality was good. We should do a good job in the timely harvest to achieve the goal of nine yellow crops and ten harvests, high yield and high quality.
