We all like to eat fresh sweet corn, the market capacity is large, high yield, good efficiency, from sowing to fresh harvest about 90 days, does not affect the hybrid rice cultivation, is the production of 1000 kg per mu grain, grain type planting Good mode. To summarize the practice of cultivation in recent years and planting good sweet corn in spring, we should grasp the following:
one. Use improved varieties
At present, the sweet corn varieties promoted in Henan are mainly Super Sweet No. 3 and Super Sweet 204, and new varieties such as Dongtian 206 can also be tested. These varieties have high yields, medium growth periods, fresh grain sugar content of more than 16%, and fresh food tastes good.
two. Timely sowing, cultivating strong seedlings
Generally from the 15th to the 20th of March onwards, sowing must be carried out with nylon film covering the nursery. Choose soil with loose soil, good fertility, and sunny sandy land as seedbed. After fine soil preparation, apply thin manure fertilizer once more, arrange maize seeds at a grain spacing of 3-5 cm, slightly suppress and cover with fine mud. , about 1 cm thick, and then cover the film insulation. The seedling age is about 20 days, and the leaf age is 2 leaves from one heart to three leaves as one heart to prevent overage transplanting and reduce yield.
three. Improve soil preparation and transplanting quality to ensure full seedlings and seedlings
Before the ploughing, 25-30 kilograms of ammonium bicarbonate was applied and 25 kilograms of calcium phosphate was added. After the ploughing, the soil preparation works, and two rows of 1.2 meters wide (even ditch) are planted. The soil with heavier soil can be filled with fertilizer at one time. That is, 75 kg of ammonium bicarbonate, 25 kg of superphosphate, 15 kg of potassium chloride, and 80% of grass in the mu after covering the soil in the middle of the ravine. 100 ml of amine water was evenly sprayed on the surface to prevent weeds, and then covered with plastic film to be planted. However, in the case of heavy sand leakage, fertiliser should not be applied at one time. Fertilizer should be applied according to the principles of “appropriate application of seedling fertilizer and heavy application of fertilizersâ€. Corn seedlings were planted, then watered with 50% phoxim or 40% chlorpyrifos 1000 times to control the underground pests, and then cover the ground to ensure survival. The transplanting density was 3300-3500 strains, and the spacing was about 33 cm. After transplanting and surviving (about 7-10 days after planting), Miaofei should be applied in a timely manner. Generally, 10 mu of ammonium sulfate or 10 kg of ammonium sulfate can be used in the mu.
four. Strengthen management
Sweet corn varieties have multiple spikes and they should be removed in time, leaving one strong ear per plant. In the horn period, the corn borer was treated with 600 times of bt emulsion (Bacillus thuringiensis) or 500% of 18% of insecticidal doubles or 1000 times of 90% crystals of trichlorfon. It is forbidden to use highly toxic and high residue pesticides. The use of any pesticide should be stopped 15 days before harvest.
Fives. Sweet corn should be isolated from ordinary corn
The requirement of more than 300 meters interval to prevent the string of flowers affect the quality of sweet corn, fresh sweet corn can be sowed in batches, in order to continuously supply the market, to avoid a one-time maturation amount is too large, resulting in losses.
Many people believe that the mushroom soup is delicious. Why do mushrooms taste so fragrant? According to He Jiguo, this is mainly because mushrooms are rich in delicious amino acids. The sources of umami in mushrooms are mainly flavorful amino acids such as glutamic acid and aspartic acid, as well as taste nucleotides such as inosinic acid and guanylic acid. These substances make mushrooms taste delicious, comparable to meat .
