What corn is good to grow in the countryside? Corn is often grown in rural areas, but what is the be

It is necessary to comprehensively consider the local soil fertility, light and temperature conditions, yield requirements, farming habits, management level, irrigation conditions and other factors, and select varieties with suitable growth period, high yield, stable yield, stress resistance and suitable for mechanization. Specifically, it can be divided into the following types:

1. Varieties with high yield potential such as Denghai 605 and Qingnong 11 can be used for small-area high-yield research fields to fully tap the local high-yield potential;

2. Large-area demonstration fields can use varieties such as Zhengdan 958, Qingnong 11, Denghai 605 and other varieties that are dense-resistant, lodging-resistant, high-yield and stable-yielding;

3. Ordinary farmland planting is resistant to dense planting, lodging resistance, suitable for mechanization, high yield, stable yield, strong stress resistance, Zhengdan 958, Qingnong 11, Denghai 605, Tiantai 33, Yuyu 30, Jiyu 901, Nongxing 207, Hualiang 78, Huasheng 801, Deka 517, Ludan 9088, Liansheng 216, Bangyu 339 and other varieties;

4. Silage corn can be planted with varieties with high biological yield, such as Yuyu No. 2, Denghai 605, and Dedan No. 5;

5. Fresh corn can be planted with varieties with good taste, color and appearance, such as Qingnong 206, Xixing Wucai Xiannuo and Jinuo 33;

6. Grain machine harvesting can be planted with Ludan 2016, Yuyu 30, Deka 517, Xinrui 25, Jinlai 376, Jingnongke 728 and other varieties with moderate growth period, fast grain dehydration, moderate ear position and strong lodging resistance.

It is believed that this phenomenon is common in rural areas, in fact, corn, red shaft and white shaft, there is no difference between high and low yield, just that the characteristics of the two are not the same, the plant of red shaft corn grows relatively large, lodging resistance is also relatively strong, the dehydration speed is relatively fast, suitable for machine harvesting, but the biggest disadvantage is not heat tolerance, if there is high heat weather, especially in the pollinator period, the impact on corn yield is very large, easy to appear premature aging and protruding phenomenon, in the Huanghuaihai area must be cautious to use red shaft varieties.

Although the lodging resistance of the white shaft corn is relatively weak, and the dehydration of the seed rate is relatively slow, the disease resistance is relatively strong, the seed yield is relatively high, and there will be no protruding phenomenon, and the yield is relatively stable.

Farmers in Shandong, what varieties are you going to choose for planting corn this year? Among the above varieties, is there one suitable for you?

It is best to plant waxy corn in rural areas, because waxy corn is relatively simple to plant, and waxy corn has a particularly strong growth ability, which does not require much effort.

Choose seeds that are suitable for your own soil and water source. The fertility of each local plot is different, and the choice is also different. High-yielding varieties should be selected for plots with good fertility, and varieties with drought tolerance and thin ridge tolerance should be selected for medium and lower fertility.

Generally, you can plant ordinary corn, because ordinary corn can be better absorbed, and then it is also very widely used, it is not too strict for its own geographical environment and feed requirements, and it is easy to feed, and the annual output is also very large.

Of course, the corn grown with a seeder will be better, because the distance between the corn planted with the seeder is particularly even, so the corn grown is also very full.

Plough the soil. In corn planting technology, in order to make the root system of the plant better rooted in the soil, it is necessary to plough the planting soil, and meticulous tillage can make the corn seedlings adapt to the new environment faster, and they must be ploughed in suitable weather; It is about 15 centimeters of ploughing.

First, choose excellent varieties.

In order to obtain high yield of corn, variety is the key, and variety accounts for about 19% of the influencing factors of corn yield. Excellent corn varieties mainly include the following aspects:

1) Good adaptability: when purchasing corn varieties, we must choose the corn varieties approved by the three major corn producing areas of the country, such varieties have been produced and planted for many years, with good adaptability, strong ability to resist bad weather, and easy to obtain high yield.

2) Developed root system: corn grows in high temperature and rainy summer and autumn, in the whole growth and development process, it needs to experience drought, high temperature, heavy rain, strong wind and other bad days, the root system is developed varieties, the ability to absorb water and fertilizer is strong, the aerial roots are developed, the root system is firmly gripped, and the ability to resist natural disasters is strong.

3) Live tree maturity: live mature varieties not only have strong lodging resistance, are not easy to lodging, but also have a long grain filling time and high 1000-grain weight in the later stage, which is the guarantee for corn to obtain a bumper yield. At the same time, it is also convenient for mechanical harvesting.

2. Apply more nitrogen fertilizer.

At present, the straw returning area is large, the soil contains a large amount of potassium, for corn, the potassium in the soil can meet the needs of corn, summer and autumn, frequent rainfall, nitrogen fertilizer is easy to lose, corn has the highest demand for nitrogen, and more nitrogen fertilizer can significantly improve the yield of corn. According to the test, the impact of nitrogen fertilizer on the yield accounted for as much as 26%, more than the impact of seeds, corn to get 1500 kg of yield, 30 kg of urea per mu, to get 1800 kg, more than 40 kg of urea per mu.

3. Take the medicine more often.

Corn plants are tall, the field ventilation and light transmission are poor, lodging is most likely to occur in the middle and late stages of growth, and the mixed occurrence of a variety of pests and diseases is serious. Lodging and pests and diseases are the main causes of reduced corn yields. Therefore, the traditional method of spraying only once to control the drug was changed to spraying the medicine twice, and at the same time adding the pest control agent.

It can be sprayed with the first time to control the growth of the agent and insecticide when the corn 6 leaves, shorten the length of the basal internode, improve the lodging resistance of the corn, and spray the control of the drug plus insecticide and fungicide again in about 10 leaves of the corn, appropriately reduce the height of the ear, shorten the distance of nutrients, which is conducive to the formation of a stick, and can also reduce the occurrence of diseases and pests in the later stage.

Fourth, delay the harvest.

The temperature of corn grain filling period gradually decreases, the grain filling time will be extended, and the delayed harvest can prolong the grain filling time of corn grains, increase the 1000-grain weight of corn, and make corn fully mature. The grains are full, the color is bright, the hardness is strong, and the appearance quality is also better. According to the test, in the Huanghuaihai area, the corn harvest is 10 days late, the yield per mu can be increased by more than 50 kilograms, and the income is increased by 100 yuan, and the best harvest period of summer corn in the Huanghuaihai region should be on October 10, and the yield will be reduced in advance, and the yield that is about to arrive will be lost in vain.

When planting summer corn, only need to pay more attention to the above points, do not need more input, the yield per mu can be greatly improved, according to the test, the maximum income per mu can reach 500 catties, almost equal to half an acre of land.

1. Cultivating and weeding. The seedlings should be shallow and the rows should be deep. Although cultivating will cut off some fine roots, it can promote the growth of new roots and control the vigorous growth of aboveground parts. Interplanting corn fields are generally more compacted at the seedling stage, and should be cultivated in time after wheat harvest, remove wheat stubble, and break the compaction.

2. Squatting seedlings to promote growth. Squatting seedlings should start from the seedling stage to the end before jointing. And spraying seedlings with a new high-lipid film can prevent bacterial infection, improve the ability to resist natural disasters, improve photosynthesis intensity, and protect the growth of seedlings.

Squatting seedlings should master the principle of "squatting black but not squatting, squatting fat but not squatting thin, squatting dry and not squatting wet". The sowing and growth conditions of interplanting corn are poor, and it is generally not suitable for squatting seedlings.

3. Water and fertilizer management. Phosphate fertilizer is best applied before 5 leaves, so we should do a good job in water and fertilizer management to promote weak to strong. Phosphorus, potassium fertilizer and organic fertilizer should be applied as soon as possible before and after seedling setting combined with tillage.

In addition, before the heading stage of maize, Zhuang Ear Ling was sprayed to strengthen the physiological function of crops, improve the quality of pollination, fertilization and grain filling, and increase the 1000-grain weight.

4. Pest control. There are many types of pests in the seedling stage of maize, especially summer maize. At present, the main pests that harm corn at the seedling stage are ground tigers, aphids, thrips, cotton bollworms, lamp moths, wheat straw flies, etc., and the insect situation should be detected and reported in a timely manner, and the pests should be prevented and controlled in time.

At the same time, it cooperates with the spraying of the new high-lipid film to improve the utilization rate of the active ingredients of the agent and consolidate the control effect.

1. Seed selection and treatment.

Corn seeds should choose compact varieties with strong disease resistance, high yield, and lodging resistance, and try to leave high-quality and full seeds, and the seeds need to be dried and coated and soaked before sowing.

2. Suitable sowing period.

The time of corn sowing should be selected at the right time for sowing, and April is the best sowing time. In general, low-fertility soils are planted in equal row spacing. In fertile areas, a combination of wide and narrow methods can be used to plant to make full use of soil fertility and increase corn yield.

3. Scientific fertilization.

For the relatively weak growth of corn, urea and phosphorus and potassium fertilizers need to be supplemented in time to effectively improve the growth rate of corn and improve corn yield.

4. Cultivating and weeding.

The purpose of cultivating is to improve the permeability of the soil, reduce the risk of soil diseases, and then weed in time, which can greatly improve the growth quality of the corn itself and make the corn more plump.

5. Pest control.

Corn is prone to smut, large and small spot disease, stem rot and other diseases during the growth process. Aphids, corn borers, and other pests love to bite corn stalks. Therefore, farmers should pay attention to strengthening field management and taking pest control measures in a timely manner.

Different pests and diseases have different pesticides and control methods, so as to effectively increase the yield of corn.
