Cowpea must be temperature-controlled for the first three days after sowing to emergence, which will help rapid emergence and ensure the robustness of the seedlings. The temperature in winter is low. After the mulch is covered, the water evaporates slowly. From seeding to emergence, no watering management is needed. So, how should cowpea be managed after emergence?
Pre-emergence insulation
Cowpea is most sensitive to temperature response before and after emergence, but after the emergence, the nutritional consumption of the seeds is exhausted, and if the seedlings continue to grow, organic nutrients produced by photosynthesis are needed.
The period from the winter solstice to the great cold and solar terms is also the time when the temperature is the lowest and the light time is the shortest. Under these conditions, after the cowpea emerges, it must first ensure sufficient light to cultivate strong seedlings and improve seedling quality.
From the unearth of seedlings, vegetable farmers should adjust management strategies in a timely manner according to weather conditions. In the case of low temperature and low light in winter, first of all, ensure the light:
One is to pay attention to the high light transmittance of the multilayer cover film. In the seedling sheds of many vegetable farmers, the outer film should be provided with a dust-removing cloth strip to remove the film dust at any time. If there is a difficult place to clean, the vegetable farmers should wash or scrub with water to ensure the outer film light transmittance. The film covered by the inner layer, Master Zhang specially reminded that you must choose a new film, not the old film retained in previous years. The old film has a lot of dust and the light transmittance is greatly affected. It can be used in other seasons, but it cannot be used in late winter.
The second is to pay attention to artificial light. The area of ​​the seedbed is limited, artificial light supplementation is completely achievable, and the cost is not high. It is best to choose a special vegetable fill light for artificial fill light, which has high illumination efficiency and less waste, which is the best choice. If there is no special supplementary light, it can also be replaced by ordinary incandescent lamp. It also has the function of warming up while supplementing the light. However, the commonly used lighting fluorescent lamps cannot be used, because their design mainly considers the needs of the human eye, but it does not meet the needs of vegetable growth. In the haze weather similar to the previous few days, vegetable farmers can turn on the lights for 5-6 hours during the day to avoid weak cowpea seedlings and poor root system development, laying a foundation for subsequent cultivation of strong trees, high yield and high quality.
Properly fertilize and promote seedlings
After emergence, as the root system expands, the seedlings begin to absorb nutrients from the substrate in large quantities. However, at present, vegetable nursery seedlings are mostly used in 50-well plug trays. The number of filled substrates is very small and the nutrients are insufficient. After the cotyledons are flattened, the nutrient supply in the substrate begins to be insufficient. Strong growth.
After the seedlings are ready, the vegetable farmer begins to sprinkle water for the first time. At this time, 2000 times the suspension calcium of Ishihara Taurus and 1000 times the solution of Bacillus subtilis can be added to the water. Prominently, biological agents such as Bacillus subtilis can coexist with the root system, promote root growth, inhibit bacterial proliferation, and promote root disease prevention. During the second watering, you can choose high-quality water-soluble fertilizers, supplement nitrogen, phosphorus, potassium, and trace elements to promote seedling growth.
