The corn seedlings that are supplemented cannot keep up, usually due to poor growth environment, improper seedling management, diseases and pests, etc. To solve this problem, the following measures can be taken:
Improve the growing environment: The growth of corn seedlings requires sufficient sunlight, water and nutrients. If the growing environment is poor, such as insufficient light, insufficient water or insufficient nutrients, it will lead to slow growth of corn seedlings. Therefore, it is necessary to ensure that corn seedlings grow in a suitable environment and keep the soil moist, and pay attention to timely drainage to prevent the soil from becoming too wet.
Strengthen seedling management: In the corn seedling stage, it is necessary to carry out the work of thinning, seedling determination and top dressing in a timely manner. Interseeding refers to pulling out some seedlings in crowded places to improve the growth environment of seedlings. Seedling determination refers to the classification of the remaining seedlings and the selection of robust seedlings for cultivation. Top dressing refers to timely supplementation of nutrients during the growth of seedlings to promote the growth of seedlings.
Control of pests and diseases: Corn seedlings are susceptible to pests and diseases, such as aphids, borers, etc. These pests and diseases can suck up corn juice, causing corn seedlings to grow slowly. Therefore, it is necessary to regularly check the growth of corn seedlings, find pests and diseases in time and carry out control. Methods such as biological and chemical control, such as spraying pesticides or stocking natural enemies, can be used.
Increase the amount of sowing appropriately: If the amount of corn is sown too little, it will cause the growth of corn seedlings to be slow. Therefore, the amount of sowing can be increased appropriately to ensure that there are enough seedlings for cultivation.
Choosing the right variety: Different varieties of maize have different growth rates and disease resistance. Therefore, when choosing corn varieties, it is necessary to choose varieties that are suitable for the local growing environment, and understand information about their growth characteristics and disease resistance.
Timely drainage and flood prevention: Corn needs sufficient water during growth, but too much water can also affect its growth. In areas with more rainfall, it is necessary to drain water in time to prevent flooding to avoid excessive soil moisture and adverse effects on corn growth.
Proper fertilization: Corn needs sufficient nutrients to grow, but fertilization should also be reasonable. Too much or too little fertilization can adversely affect corn growth. When fertilizing, it is necessary to carry out a reasonable ratio and application according to soil fertility and corn growth needs.
In short, in order to solve the problem that the corn seedlings can not keep up, it is necessary to start from many aspects, improve the growth environment, strengthen the management of seedlings, prevent and control pests and diseases, appropriately increase the sowing amount, select appropriate varieties, timely drainage and flood prevention and reasonable fertilization and other measures can promote the growth and development of corn. At the same time, we should also pay attention to the growth of corn, find problems in time and deal with them.
