According to climate characteristics and planting conditions, corn seedling management should be based on the increase of Miaofei, and promote the rapid growth of seedlings as the center, early management when the time of grab, to reach the purpose of seedlings, seedlings uniform, Miao Qi, Miao Zhuang. Specific management measures are as follows:
Seedlings fill seedlings. After emergence of corn, timely inspection of seedling emergence, emergence of seedlings and ridges must be transplanted in time for replanting. It is advisable to replant seedlings with 3 to 4 leaves visible. Replanting seedlings can be used to superfluous seedlings before seedlings. Replanting is best done in the afternoon or on cloudy days. Immediately after transplanting, watering is necessary to ease seedlings and increase survival rate. When the seedlings in the field are not enough, in order to reduce the time for seedling renewal, measures can be taken to stay close to two plants in order to strive for agricultural time.
Machine sowing corn field, to early morning seedlings, Dingmiao seedlings, over dense seedlings, visible in 3 to 4 leaves between the seedlings, 6 to 7 can be seen leaf Dingmiao, interplanting plots can be in 5 to 6 leaves visible Dingmiao, Dingmiao When weed out weak seedlings, seedlings, diseased seedlings, and mixed seedlings, we chose to keep the same size of healthy seedlings to achieve a reasonable density of seedlings. When the density is not enough, it can be compensated by the method of leaving two plants in the acupuncture points. Dingling time should be appropriate, Dingmiao too early to find disease seedlings, hybrid seedlings, weak seedlings, large seedlings, seedlings; Dingmiao too late to cause crowded seedlings consume nutrients, easy to form yellow seedlings, weak seedlings.
Timely top dressing promotes seedling growth. Insufficient base fertilizer or application of fertilizer plots, to make timely recovery Miao Fei. Iron hoe planting plots, can apply urea 5 ~ 10 kilograms or so, interplanting plots can be seen in the seedling stage leaves 6 to 8 leaves before, Mushi potassium chloride 5 kg, urea 5 to 10 kg. For the unfunged plots, we can combine the recent rainfall conditions and seize the time to top-dress.
Timely prevention of pests and weeds. Maize seedlings prone to diseases and pests are mainly rough dwarf disease, Laodelphax striatellus, armyworm, thrips, cotton bollworm, golden needleworm, cultivating sunflower alum and so on. According to plant protection station forecasting and prevention and control technical advice timely prevention and treatment.
The interplanting and shoveling of the sown corn field seriously harm the grass and weeds must be chemically treated in time to avoid grass shortage. Weeding can also effectively control the parasitic diseases and insect pests on the weeds. After spraying, the herbicide-free plots are not sprayed before. Herbicides must be selected for chemical herbicides. The best method is to use corn in the 3 to 5 leaf stage. Use the pesticides strictly in accordance with the period of application, the amount of pesticides, and the method of operation. There is a phytotoxicity.
