At present, it is the season for sowing peanuts in the northern region. In the past two years, the peanut planting areas in Liaoning and northern Hebei have experienced problems of low seedling emergence in different degrees, and even worse, the phenomenon of bad seeding in individual places. Some farmers have consulted experts on the phone several times. Why is the emergence rate of peanuts low? How can we preserve the issue of seedlings? For this, the newspaper invited experts to answer one by one.
Why is the emergence of low peanuts native to South America, is a warm crop. Seed characteristics: First, large-grained kernels, 100-grain weight averages over 50 grams, and some varieties can reach 80 grams or more. The second is that the seeds have dormancy characteristics and must be fully stored after a certain period of storage and after-ripening. Peanut seeds from the germination to emergence of the soil of water, gas, heat conditions more stringent requirements, only to meet its requirements to do a good job before sowing and sowing the series of work before they can guarantee the whole seedlings.
To preserve seedlings requires stricter environmental conditions. One is temperature, the lowest germination temperature is 12°C. There are differences among different species, for example, the minimum temperature for the germination of M. subspecies is 15°C; the effective accumulated temperature for the subspecies of subspecies requiring more than 12°C from sowing to emergence is higher than 115 °C. However, the change in temperature after spring sowing peanuts is repeated, which is not conducive to emergence. Peanuts need 10 to 20 days from sowing to emergence. The minimum temperature required for peanuts to enter the seedling stage is 14°C~16°C. The second is that the seeds should absorb water, and they can only germinate after sufficient water swelling. Peanuts need to absorb four times the weight of the seeds themselves to germinate from germination to emergence. Therefore, in order to ensure the proper humidity of the soil before and after sowing, we must ensure that the farmland is protected. The third is the ventilation condition. During the peanut germination process, oxygen consumption is more. If the oxygen content in the soil air is too small, the emergence will be affected. These requirements determine peanuts like sandy loam with deep soil, loose ventilation, good water seepage, and rich organic matter.
In addition to environmental conditions, seed quality is also important. After selecting a good seed and carrying out seed treatment, first the seeds must be sunburned to increase the seed viability; timely shelling should not be premature, and sowing should be done on the day of or after the last day of sowing;
The key technical measures should be planted in a timely manner: Do not blindly seek early, encounter low-temperature weather, and can appropriately postpone the sowing. The selection of sowing dates depends mainly on the temperature conditions. Only if the temperature is stable at 12°C~14°C or more, do you insure yourself.
Whether or not to soak germination before sowing, should pay attention to the conditions at the time, in the soil moisture is good, low temperature, appropriate or early sowing, no soaking germination. Only when appropriate late sowing and good lyricism are soaked germination. In addition, appropriate seed germination and seed dressing, inoculation of Rhizobium, etc. can be applied during reseeding; soil conservation measures after sowing before sowing are important foundations for the whole seedlings; the depth of sowing should be moderate, and the sowing of peanuts and sowing of single seeds should be two methods. Seed sowing 2 seeds, sowing depth should be adjusted according to the soil moisture conditions, moderate sowing depth should be about 4 cm; depth adjustment is not shallower than the shallowest 3 cm, the deepest is not deeper than 7 cm; peanut seed fertilizer should be used Calcium, phosphorus diammonium or low nitrogen and high phosphorus potassium fertilizer varieties. Single urea or high nitrogen urea-based compound fertilizers should not be used. In some areas, calcium fertilizer should be taken into account to prevent the appearance of empty shells; the problem of spring sowing of peanuts is mainly caused by two aspects. The external cause is that the temperature in spring is rising slowly and unstable, and peanuts will suffer cold and cold after they sow. Wet double stress, which is not good for the emergence of thermophilic peanuts. The internal reason is that peanut seedlings have high requirements for environmental conditions (mainly warm, wet, and oxygen). If some sowing dates are too early and pre-soaking and germination are carried out in advance, there will inevitably be different levels of rotten species.
In a word, in the high-yield cultivation of peanuts, reasonable sowing is a key link. Only by doing seed processing, grasping the sowing date, sowing depth, reasonably selecting the varieties of seed fertilizers and correctly applying soaking and germination techniques, etc., can we achieve full peanut seedlings, Lay the foundation for high yields.
The Platewarmer uses minimum of energy due to the grid design of the heating element and provides a practical way to heat 3-12 plates in less time than it takes to cook a meal, leaving room in your oven for the cooking. To use the Plate Warmer, simply place up to 4 plates in each fold and switch on.
Electric Plate Warmers are thermostatically controlled to keep the plates at the ideal temperature to serve hot food whilst leaving the outer edges safe to handle and are a safe and easy alternative to heating up plates in the oven. The Electric Plate Warmer can be personalised with your own bespoke logo and/or design colour.
