Corn is the main cash crop in our country, many areas are planted, in the process of planting corn, farmers are most concerned about quality and yield, so according to the different periods of corn growth to do a good job of corresponding field management. So how to strengthen the management of corn seedlings? Let's find out.
Watering promptly
After sowing, corn should be watered in time to facilitate the emergence of seedlings and ensure that the seedlings are complete and even.
Investigate the field and replenish the seedlings
Due to the quality of corn seeds and soil conditions, the sown corn will be sown with varying degrees of lack of seedlings and broken strips, which will seriously affect the yield of corn. After the emergence of seedlings, it is necessary to often go to the field to check the seedlings, and if the lack of seedlings is found, they should be replanted or transplanted in time.
Seedlings and seedlings
If the sowing density in the field is large and exceeds the appropriate density of the variety, it is recommended to carry out seedling thinning and seedling setting to prevent the seedlings from being overcrowded, the root system between the plants is staggered, and the water and fertilizer are staggered, which can not form strong seedlings and cause lodging in the later stage. Seedlings and seedlings are generally carried out in the afternoon on sunny days, and diseased seedlings, insect bite seedlings and stunted seedlings are more likely to wilt in the afternoon, which is easy to identify and eliminate.
Cultivating and weeding
Cultivating and weeding can loosen the soil, increase the ground temperature, accelerate the decomposition of organic matter, increase the effective nutrients, and is conducive to drought prevention and moisture preservation and removal of weeds in the field. Generally, it should be carried out three times, the first time before the seedling, when the seedling is 4 5 leaves, and the depth is 3 45 cm; the second time after the seedlings are set, when the seedlings are 1 foot high; The third is carried out before jointing, 9, 12 cm deep. Ecological planting and artificial weeding, although it is a time-consuming and laborious method, is what every Yiye Qiugu people are willing to adhere to, not only to provide high-quality and high-nutrition corn, but also to pass on the life concept of "returning to the essence, natural simplicity" to people who love life.
The above is the key points of field management of corn seedling stage, corn as an important food crop, in the case of increasing planting costs, only scientific planting, careful management, in order to achieve high yield and high quality and control costs.
