How many days does corn mature? how can corn be planted with high yield?

As we all know, corn is a kind of coarse grain that we human beings often eat. in fact, it is also a raw material for animal feed. So in today's market, the demand for corn is very high. So many people start to plant corn, so how many days will it take for corn to mature? And what little secret do we have to achieve a high yield of corn? Next, the editor will teach you.

How long does the corn ripen?

1. Precocious ones are "Ji Chengdan 3" fresh food for 60 days. It can be harvested in 75 days.

2. Medium ripe "Huang 417" can be eaten fresh in 80 days and harvested in 100-110 days.

3. The growth period of summer sowing in Huang-Huai-Hai area of "Zhengdan 985" is about 96 days. Spring sowing for about 128 days, there are many varieties, the harvest time is about the same.

4. There are also some waxy corn and fruit corn, which are also divided into middle and late ripening. Generally speaking, the days of fresh food are between 65 and 90 days.

How to plant corn for high yield

1. For high-quality seeds, the purity should be high, not less than 98%, and the bud rate should be high, not less than 95%. Most ordinary corn seeds can not meet this requirement. You can't pick one by hand.

2. The greatest success of single-grain sowing is to achieve a scientific planting density. A variety can have the highest yield only under reasonable density, and it can not be high-yielding even if the density is high or low. High density will also cause lodging, empty pole, susceptibility and other problems, resulting in varying degrees of production reduction. If it is too thin, the production will be reduced, but there will be no problem of toppling the empty rod.

3. Sowing and protecting seedlings is the key, improper sowing methods will cause lack of seedlings and break ridges, and then affect the density and yield. The problems of burning seeds with chemical fertilizer and sowing rotten seeds are the main factors leading to seedling deficiency. Only plots without irrigation conditions must be sown deeply to reduce the impact of drought on seedling emergence. Plots that can be watered at any time must be sown shallowly, with a depth of no more than 5 cm, and 3 cm is the best.

Misunderstanding of Maize sowing

1. Ordinary seeds can be used for single sowing. Many farmers are not interested in single sown seeds and think that ordinary seeds can be used as single sown seeds by bumping them with a dustpan and picking small seeds.

2. Set the row spacing at random, have no concept of density, and always think that it is better to be thick than thin. There are many hands to transform the seeder into a structure that can adjust the row spacing at will and sow seeds according to the line spacing of 50 cm. The distance between plants was set to 17-18 cm.

3. It is OK to plant fertilizer well. Pour the head water to flood irrigation. If the sowing is too shallow, the deeper the sowing, the better.

Misunderstandings in the use of Maize herbicides

1. Do not know the type and use period of corn herbicides, spray and use them indiscriminately. The mixed use of herbicides, organophosphorus pesticides and micro-fertilizers can save labor.

2, do not follow the prescribed dosage, increase the dosage at will, and try to buy eliminated herbicides cheaply.

3. Use a motorized sprayer to spray the medicine quickly, and spray it again before you run out of medicine.

In the above, the editor also taught you how to sow corn, which can achieve a high yield. As a matter of fact, it is very hard for farmers to grow crops. The so-called a drop of sweat, a grain of grain. In our daily life, we should learn to cherish food and put an end to waste.
