The technique of planting Malting Barley

Malting barley is the main raw material for brewing beer, and there is not much difference between malting barley and forage barley in morphology. Let's take a look at the techniques of growing malting barley

1. Land selection and preparation

Malting barley has a wide range of soil adaptation, loam and light loam can be planted, and green manure, beans, corn, oil sunflower and other crops are good for the previous crop. It was determined that the organic matter content was 1.3%, alkali-hydrolyzable nitrogen was 57 mg/kg, available phosphorus was 7 mg/kg, available potassium was 140 mg/kg, water was sufficient, and the plots with medium and high soil fertility were most suitable for growing malting barley.

In order to get early sowing at the right time, it is better to cultivate barley in autumn, turn it in autumn, and complete it before winter.

II. Preparation before sowing

1 Fertilization

Fertilization of malting barley, in addition to improving yield, should also take into account the improvement of quality, fertilization should adopt the practice of "heavy base fertilizer, good seed fertilizer, early seedling fertilizer", base fertilizer using organic fertilizer and inorganic fertilizer combined, inorganic fertilizer, nitrogen fertilizer more than 80% as base fertilizer, phosphorus fertilizer except a small amount as seed fertilizer, the rest as base fertilizer.

2 Seed treatment

At present, the beer barley varieties suitable for planting in Tacheng City mainly include: Xinyin D8, Ganpi 4, Xinyin D5, etc.

The seeds were treated with carbendazim before sowing to control barley smut.

III. Sowing

1 Early sowing at appropriate time

Malting barley is an early spring crop, suitable for growing in cold weather conditions. The suitable sowing date in Tacheng City is about April 12.

2 Sowing methods

667 m 2 sowing rate of 12-15 kg. 24-row seeder is used for sowing, 1.2-meter small ridge is used for sowing, row spacing is 15 cm 2, shallow sowing is beneficial to emergence, seeds are required to be evenly planted, sowing depth is consistent, sowing row ends are straight, and soil covering is good.

IV. Field management

Barley growth period is short, growth and development speed is fast, field management measures should be appropriately advanced, early tube to promote early onset. For wheat fields with large population, proper seedling control should be carried out at jointing stage to prevent lodging.

1 irrigation

Irrigation in growth period should adopt the principle of "early irrigation, frequent irrigation and light irrigation", pay special attention to irrigation in seedling stage, jointing stage, booting stage and filling stage, and start irrigation at 2 leaves and 1 heart. During the whole growth period, increase the number of irrigation times and reduce the amount of irrigation, on the one hand, prevent water shortage and early, on the other hand, prevent waterlogging phenomenon caused by flood irrigation.

2 enrichment

Barley seedlings weaning early, so more fertilizer should be applied in advance, the amount of nitrogen fertilizer should be strictly controlled in the middle and late stages, and foliar fertilizer such as potassium dihydrogen phosphate should be sprayed in the late heading stage of barley, which has the effect of preventing dry hot wind and increasing 1000-grain weight. Due to thin stems, high-yield fields are easy to lodge. To prevent too many tillers and too large populations, chlormequat should be sprayed before jointing to inhibit the elongation of basal internodes.

3 Pest control

667 m 2 seedling spraying mules 50 g, tribenuron-methyl 50 g, mixed foliar fertilizer spray control weeds.

667 m 2 was sprayed with 80 g of copper triazole in water to control rust, and 667 m 2 was sprayed with 80 g of carbendazim in water to control net spot.

667 meters 2 with dimethoate 80 grams of water spray control aphids, generally sprayed twice. At the same time, mixed potassium dihydrogen phosphate and Fengleding foliar spray, in order to facilitate the full seeds, play a role in anti-dry hot wind.

5. Timely harvest

Barley harvest is suitable for late wax ripening, harvest early.
