The latest management methods of maize seedling stage

Corn is one of the most important crops in China, and it has a wide range of use, such as edible, oil, feed and so on. Corn has strong adaptability to the environment, coupled with the strong function of hybrid corn seeds, so we can see a bumper harvest of corn every year, so do you know what to do in the seedling stage of corn to make corn grow faster and better? The following is the management method of corn seedling stage that pro-agricultural network would like to share with you today, hoping to help more partners who love corn planting.

1. Replenish seedlings with intermediate seedlings

The first step of corn field management is planting, and planting includes checking seedlings, replenishing seedlings, interplanting and fixing seedlings, of which the most important work is interseedling and seedling replenishment. About a week after the emergence of corn seedlings, we need to check the emergence of corn seedlings in the field. If there is a lack of seedlings, we need to replenish the seedlings in time to ensure the seedlings in the field. The second is to check whether there are dense corn seedlings in the field. Pull out some of the more dense areas, and transplant reasonably. It is planted at a distance of 40 to 50 centimeters between rows and 30 to 40 centimeters between plants.

2. Water management

Watering is needed after planting, because the transplanted corn seedling does not really survive, so it needs to provide enough water to promote its root growth. usually, there is no rain after planting, so it needs to be watered at least every four to six days or so until it grows new roots and fully adapts to the new environment. Finally, it is necessary to reduce moisture after the corn seedlings survive, because its waterlogging resistance is very poor during this period, and the soil needs to maintain a certain degree of dryness. If there is rainfall during this period, then drainage should be carried out in time, otherwise the corn seedlings will rot and die.

3. Ploughing and weeding

At least two times of intermediate ploughing and weeding are needed during the growing period of corn, and the first intertillage is usually carried out about seven to ten days after corn planting. First, it can enhance soil permeability, secondly, it can promote the development of maize seedling roots, and finally, it can reduce the absorption of nutrients by weeds. The second weeding is usually carried out when the corn seedlings grow to about 40 centimeters, mainly to promote the growth of the plant and accelerate the growth rate of the plant.

4. Topdressing seedling fertilizer

We usually call the period from the emergence of corn to the time before corn cob is called seedling stage, and the seedling fertilizer we are talking about is mainly to promote the growth of corn seedlings, in which seedling fertilizer can be divided into Qi seedling fertilizer and seedling fertilizer. Qi seedling fertilizer is usually carried out about ten days after corn planting, while raising seedling fertilizer usually has to wait until the corn seedling grows to about 40 to 50 centimeters, and each time it is best combined with ploughing and weeding. The composition of seedling fertilizer mainly includes urea, potash fertilizer, phosphate fertilizer, compound fertilizer and so on, mainly by hole application, which can enhance the Russian utilization and absorption of nutrients.

5. Pest control

In fact, the greatest harm to corn seedlings is some underground pests, such as grubs, ground tigers, etc., followed by some leaf worms, such as rollers, thrips, and finally seedling blight, root rot, and so on. all these pose a great threat to the growth of corn seedlings. For underground pests, we usually use phoxim to irrigate roots, while aboveground pests can be controlled with imidacloprid, we can use carbendazim to control seedling blight, and mancozeb should be used for root rot disease. secondly, we must strengthen the management of water and fertilizer in the field.
