Technical guidance for beet spring production in 2020

The National Agricultural Technology Extension Service Center of the Ministry of Agriculture and Rural Affairs, in cooperation with the Agricultural and Rural Ministry of Sugar Expert Guidance Group, has studied and formulated the Technical Guidance for the Spring Production of Beets in 2020 according to the characteristics of production in different producing areas.
production areas should do a good job in epidemic prevention and control on the basis of technical training services to ensure that various technical measures are put in place to ensure the stable development of beet production in 2020.
, before the broadcast ready to timely land, the requirements to achieve the level, soil crushing, land clean, ground solid, to meet the needs of different cultivation patterns.
1-2 days before seeding, 96% of the essential isopropyl melatonin cream can be used to control field weeds.
prepared for germination rate of more than 95% of the pill granulation of a good seed.
, seeding and seedling bed management (i) mechanical fine live planting mode.
the use of precision seeding machinery sowing, requiring straight, neat ups and downs, consistent depth, uniform soil cover.
2 cm to 3 cm is appropriate, should not be too deep.
if the soil of the plot is too empty before planting, it should be suppressed first.
to be seeded side-by-side inspection, to avoid leakage, to prevent the phenomenon of broken ridges.
the first drip immediately after planting, drip irrigation to 30 square / mu or so as appropriate, to ensure the seedling.
the seedlings, if the weeds are seriously in need of chemical weeding, the beet grows to 6-8 leaves when the field to cultivate weeds and other management work.
to seize the sowing land, such as in the early spring windy weather, should be used to increase drip irrigation belt water or mobile irrigation equipment and other methods to replenish water in a timely manner, to ensure the whole seedling.
(ii) the drip irrigation planting mode under the mechanical coating film.
5 consecutive days in the spring when the surface temperature of 5 cm is stable at more than 5 degrees C.
seeding and first drip requirements are the same as for mechanical fine-grained live planting patterns.
beet 8 leaf period, a permeable irrigation, so that the leaves quickly reached lush.
after the sowing to pay attention to the field to check seedlings, if pests occur to spray pesticides in a timely manner, improve the rate of beet seedling.
(iii) Paper tube seedling transplant planting mode to choose the windward yang, high ground, flat ground, well-drained places as nursery sites, build plastic sheds, small area can be buckled small arch sheds.
Choose fertile topsoil from wheat, corn or potato land that has not been planted for more than 5 years as nursery soil, nursery soil requires no herbicide residue, fewer weed seeds, and avoid salt-alkali soil, clay, native soil and sand.
Seeded bed soil 300 kg plus 2 kg seedling bed special fertilizer (total nutrients≥32%, N-P2O5-K2O-7-21.5-3.5, organic matter content of 20%) mixed evenly, seedling bed application soil mat height of more than 10 cm, and flat, rolled solid, avoid the use of "underground or semi-subterranean bed" nursery.
7 days after seeding, pay attention to insulation, the temperature in the shed during the day to maintain 25 degrees C-30 degrees C, at night more than 10 degrees C.
such as excessive temperature to timely ventilation, to prevent high temperature sprouting, lack of oxygen in the shed and excessive humidity caused by standing disease.
try not to water the seedling bed, spray 25 degrees Celsius warm water with the method of spraying the shed for moisturizing.
Seedling age up to 30 days - 35 days can be transplanted, before transplanting to water, so that the seedling bed has enough moisture, easy paper tube separation;
third, seedling disease and pest control seedling growth stage, with the temperature rise, field weed breeding, pests and diseases began to occur, need to be timely prevention and control.
(i) prevention and treatment of stand-up disease.
mechanical fine amount live planting mode can be sprayed prevention and control, membrane drip irrigation planting mode can be sprayed with water, paper tube seedling planting mode can be sprayed with 95% bad mold 4000-5000 times, or with 50% Fumei double wet powder 8 g-16 g water 35 kg spray.
(ii) Pest control.
timely prevention and control of beet elephant armor, slugs and ground tigers after the seedlings are planted.
planting of large fields, the earthworms and other underground pests serious plots, before the live broadcast of insecticidal particles and fertilizer mixed evenly apply.
planting of large fields, such as the seedling period found beets like armor, slugs and ground tigers serious harm, the use of directional rooting and spray control, can also be used poison bait scattered between the lines.
tube seedling planting mode in the nursery can be poison bait on the surrounding soil, but also seedling bed spray prevention and control.
agents may use 10% toxic toxatin granules 1.5 kg-2 kg, or 3% thiophosphate 1.5 kg-3 kg per acre, or 5% butthion Berwick granules 1.5 kg-2 kg, or 8% toxic venom granules 2 kg-3 kg.
(iii) the prevention and control of grass damage in the seedling period.
3-leaf-4 leaf period, 16% sweet tranquil emulsion 400 ml / mu soil spray.
week later, can again use 21% annulant ethyl ethyl jaundice 350 ml - 400 ml / mu - 20% take net milk oil 100 ml / mu or 10.8% high-efficiency cover grass oil 30 ml -35 ml / mu spray prevention and control grass damage.
