What are the cultivation techniques of barley and the key points of barley planting techniques?

1.Selected Breeds:Choose barley varieties that are suitable for wheatgrass or both, such as:

Minmai No. 2, Fudamai No. 1, Fudamai No. 2. Select seeds before sowing, select full and good color seeds, remove diseased grains, deflated grains, and rotten grains, and choose sunny days to dry seeds for 1-2 days. The purity of the seeds used for sowing is 85, clarity, germination rate 85, and moisture.

2.Soil selection:Choose flat terrain, deep and fertile tillage layer, active soil layer of more than 25 cm, and good land structure, no tillage obstacle factors. The plots selected for planting do not have excessive heavy metals. <>

3.Sowing at the right time:Under the climatic conditions of Fujian Province, when the soil temperature is 10-20, it is suitable for sowing. If the soil moisture is low, it must be watered once after sowing.

4.Reasonable dense planting:The sowing amount is generally 135-180 kilograms, and the basic seedling control is about 2.25 million hectares, which is conducive to the early soil covering of wheat seedlings and optimizing the planting space of wheat seedlings.

This helps to inhibit the growth of weeds and at the same time improve the yield and quality of wheat grass. The actual sowing amount should also be adjusted according to the sowing method, fertilization method, geographical conditions and other factors. <>

5.Proper fertilization:In the field with medium fertility, it is recommended to apply 285 kg of pure nitrogen fertilizer, 120 kg of phosphorus pentoxide and 285 kg of potassium oxide.

Considering the quality and regeneration capacity of wheat seedlings, more organic fertilizer must be applied. For the soil with poor fertilizer retention, it is necessary to top dressing many times, generally after cutting wheat seedlings, that is, top dressing is required for every 1 time to meet the vegetative growth of wheat seedlings.

6.Cut seedlings at the right time:Generally, it is better to cut seedlings at the peak of barley tillering, and the barley seedlings at this stage have less nutrient decline than the seedlings, and at the same time, they have higher biological yield, and the regeneration ability of wheat stakes is strong.

Usually, as long as it is harvested again in about 20 days under suitable environmental conditions, barley seedlings can be harvested three times during production. <>

7.Timely weeding:In order to ensure the food safety of wheat grass, herbicides are generally not recommended. Under normal environmental conditions, wheat grass has a stronger growth potential than weeds, and individual fast-growing weeds can be manually removed.

8.Field Management:Wheat seedlings production water demand is larger, to keep the field in a moist state as much as possible, especially after the seedlings are cut, to keep the soil moist, if the soil is relatively dry at this time must be watered, to meet the demand for water for the growth of wheat seedlings again.

Good afternoon!

Fertilization: 12 kg of diammonium, 3 kg of urea, 2 kg of potassium chloride per mu of barley autumn pine and no-cultivated land, a total of 17 kg per mu.

In order to improve moisture and enhance drought resistance, wheat plots are required to be suppressed 1 2 times immediately after sowing.

Barley seedlings are pressed at 3 to 4 leaves, and it is required to slow down the speed of the vehicle to press the seedlings to promote root growth and control the growth of wheat seedlings.

The weeding time of barley was carried out from the late stage of the third leaf to the jointing stage.

Disease control: According to the rainfall, soil and air humidity, 40g of fluconazole was sprayed at the heading and flowering stage of wheat.

Welcome to pay attention to the evaluation, thank you!

Barley planting areas in different planting time is also different, the planting time in the south is in the spring 2-3 months, the northern planting time in the autumn 9-10 months, planting according to the environmental climate, choose the right time for planting, can be appropriate early sowing or late sowing.

1. Treat the seeds.

When planting barley, it is best to choose the wheat seeds harvested in the current year, select the seeds with full grains and bright colors, remove the shriveled and insect-eyed seeds, dry them for about 2 days on a sunny day, stir them evenly with disinfectants, and sow them after disinfection and sterilization.

2. Plant in the soil.

Choose to plant barley in a plot with deep soil, loose soil, and convenient drainage and irrigation, plough 30 cm and apply basal fertilizer, sow the seeds by sowing, cover the dry soil and water enough to produce seedlings, and accelerate the speed of seedlings breaking through the soil and growing.

Barley planting time.

In the Huanghuai region and the middle and lower reaches of the Yangtze River, the planting time of barley is generally from mid-October to early November, and the spring sowing area is generally sown after the soil thaws.

In the Huanghuai region and the middle and lower reaches of the Yangtze River, the planting time of barley is generally from mid-October to early November, and the spring sowing area is generally sown after the soil is cleared and frozen.

In the process of wheat planting and management, we need to pay attention to the land leveling, sowing time, fertilization control and pest control. The land should be turned over to be loose and porous, drained and breathable, apply a certain amount of nitrogen, phosphorus and potassium fertilizers and trace elements, and sow seeds around September and October to prevent and control pests and diseases in time.

1. Transform the land

Before we can plant the seeds, we first need to make the land fully turned. We need to break up the clods in the soil, remove grass roots and debris from the soil, and comb the land so that the land ready for wheat planting is loose and aerated, the soil is fine, the ground is level, and the ditches are wide and straight, so that we can plant.

2. Sowing time

Depending on the variety of wheat and the region in which it is grown, the sowing time varies. Winter varieties are generally sown after October, semi-winter varieties are sown before October, spring varieties are sown around the end of October, North China is sown in mid-September, South China is sown in mid-November, and Central China is sown between October and November.

3. Control fertilization

Wheat needs to consume a lot of nutrients in the process of growth and development, and also needs a rich supply of trace elements, otherwise it will produce the phenomenon of deflated grains, dwarf and low yield. When we provide rotten farmhouse fertilizer for wheat, we should also choose to use compound fertilizers such as nitrogen, phosphorus and potassium according to the actual situation of the plant.

4. Prevention and control of pests and diseases

There are not too many pests and diseases in the early stage of wheat growth, but in the later stage of wheat growth, there will be powdery mildew, rust and other diseases begin to appear in the wheat field, and there will also be aphids, red spiders and other pests.

High-yield fertilization technology for barley.

1.Apply sufficient basal fertilizer.

Barley due to the short growth period, fast tillering, young panicle differentiation is significantly earlier than wheat, so the strong seedlings before winter play a very important role in high yield, in the fertilization should master the principle of "heavy before and then light, heavy bottom fertilizer, early top dressing". Generally, 1500 2000 kg of fully decomposed organic fertilizer is applied per mu (fresh manure can be fermented and rotted with Gymboree fertilizer starter agent, which can not only shorten the fermentation time, but also improve the nutrient conversion rate, reduce germs and insect eggs, and avoid the phenomenon of burning roots and seedlings), 15-20 kg of high phosphorus compound fertilizer, and it is best to cooperate with 1-2 kg of Gymboree microbial fertilizer, which can improve the fertilizer utilization rate, reduce the adsorption and fixation of phosphorus and potassium fertilizer, so that the barley seedlings in the early stage are early, and the barley grains are full in the later stage. Basal fertilizer should account for 72% to 80% of the total fertilizer application.

2. Skillful topdressing.

For wheat fields with poor soil quality, less basal fertilizer, late sowing and small groups, apply seedling fertilizer as early as possible before winter, apply 7 8 kg of urea or 8-10 kg of ammonium sulfate per mu, and 1 kg of Gymboree microbial fertilizer, which can speed up tillering and promote the occurrence of low-level tillering. After the year, the green manure is returned early, with kilograms of urea per mu, with 1 kilogram of Gymboree microbial fertilizer, and then a small amount of nitrogen fertilizer is applied to the seedlings at the booting stage as granular fertilizer. For higher fertility, more basal fertilizer, timely sowing, fast seeding, early tillering, vigorous wheat field to control the application of seedling fertilizer or no seedling fertilizer, after returning to green according to the seedling situation less or no nitrogen fertilizer, phosphorus and potassium fertilizer can be applied, generally 20 kg of phosphate fertilizer per mu, 7 8 kg of potassium fertilizer or 10-15 kg of low nitrogen and high phosphorus compound fertilizer with 1-2 kg of Gymboree microbial fertilizer, can extend the filling period and increase the weight of a single grain.

3.Top dressing outside the roots.

Foliar spray has a good effect on supplementing the nutrients required in the late growth stage of barley, promoting the movement of photosynthetic products into the grains, and improving the grain weight and quality of barley. Potassium dihydrogen phosphate solution can be sprayed 1-2 times during the wheat filling stage. If the soil can be measured, zinc sulfate solution can be sprayed according to the soil nutrient status and nutrients required by crops, and trace element fertilizers such as borax can be sprayed at the heading and flowering stage.

Because the Gymboree microbial fertilizer not only contains microbial flora, but also adds medium and trace elements, the Gymboree microbial fertilizer can be diluted 500-1000 times to take the supernatant and spray.

1.Selection conditions.

The seeds of barley seedlings must be scientifically selected varieties, requiring more tillers, relatively thick leaves, strong photosynthesis, and more nutrient elements.

Germination rate 95% Moisture content 13% Purity and clarity 97 .

The seeds are full, and the weight of 1000 grains is more than 30g, and there are no pathogenic bacteria.

2.Geographical conditions.

The land on which overwintering barley seedlings are planted should meet the standards of GB15618 or above. Soil fertility should meet the standard of NY T391 level 2 or above. The upper layer of the soil should be more than 30 cm thick, loose, well-structured, and rich in organic matter.

Planting overwintering barley seedlings requires a suitable climate and sufficient sunshine. The annual precipitation is more than 1300 milliliters, and the temperature must not be lower than minus 8 degrees Celsius, which can ensure that the growth period of barley seedlings in winter is 60-90 days. In the country, only Jiangsu, Anhui, northern Zhejiang, southeast Shandong and other places meet the climatic requirements of wintering barley seedlings.

3.Growing conditions.

The planting of barley seedlings should ensure a growth period of 60-90 days, so that the wheat seedlings have enough time to photosynthesize, synthesize nutrients and absorb minerals from the earth. Pesticides and chemical fertilizers should not be used in the planting process. The planting base should be far away from industrial pollution, away from air pollution, and away from domestic pollution.

The irrigation water quality during the planting period meets the requirements of GB5084, and there should be perfect field water conservancy facilities and smooth drainage and irrigation. When the daily rainfall reaches 100 mm or more, the water can be removed from the field in 2 to 3 days, and the groundwater level is below 50 cm.

4.Harvesting conditions.

When the overwintering barley seedlings grow to a height of 25-35 cm, they can be harvested.

When harvesting, manual harvesting should be used to avoid pollution during mechanical harvesting.

The harvested barley seedlings need to be packed in special bags and sent to the factory for production and processing within four hours.

A good source creates a good product, and only by strictly following the above planting standards for overwintering barley seedlings can we produce the best wheat phyll.
