What is a corn harvester, and what does it mean that there is often a saying of a harvesting party

1. Fertilizing soil fertility At the end of autumn, the corn stalks of the previous stubble will be chopped, and 50 kg of oil residue and 15 kg of phosphorus will be sprinkled per mu for winter ploughing and winter irrigation. Pre-sowing with the car operation, fine land preparation, to meet the "six characters" standard. · Second, sowing at the right time Sowing on April 10, soil moisture to ensure that the seeds germinate and emerge.

The sowing amount per mu is 2 9 kg for the female parent and 0 35 kg for the male parent, and the sowing depth is 5-6 cm. The air-suction seeder is used for 60 cm equal row spacing for sowing. When sowing, each mu is 10 cm away from the seed row, 5 kg of ternary compound fertilizer, 2 kg of urea, and 10 cm of fertilizer is sown.

3. Strengthen field management 1 Timely release of seedlings and timely seedling: After the emergence of seedlings, timely punch holes and seal holes, and replant the lack of seedlings. When the corn seedlings grow to 3-4 leaves, the seedlings are fixed, and the weak seedlings and miscellaneous plants are eliminated.

The female parent leaves the same size and robust seedlings, and each head retains 6 seedlings, that is, 5,500 seedlings per mu. The male parent left the seedlings at a ratio of 3:1 to prolong the flowering and pollination time.

The male parent leaves 5--6 seedlings per meter, that is, 900-1000 seedlings per mu. 2. Early tillage and weeding: three times in mechanical tillage and one time for manual weeding.

The first mechanical tillage of corn is carried out at present, and the depth is 12-14 cm; After the seedlings are fixed, the second machine is cultivated, and the depth is 14-16 cm. In the section.

Artificial hoeing and loosening of soil between the first and second mechanical cultivators. The third tillage was carried out after the film was removed before jointing, and the depth was 16-18 cm. After cultivating, the soil was furrowed, and 20 kg of urea and 8 kg of phosphorus were applied per mu.

3. Irrigation: Irrigation 5 times during the whole growth period, and the first water on December 6 should be watered evenly, thoroughly and without ditching. After that, water every 12-15 days or so, and the last water will be poured on August 15.

4. Foliar topdressing and pest control: 50 grams of foliar fertilizer "Green Wind 95" at the seedling stage, a total of two sprays, to promote the seedlings and enhance the resistance of plants; Before and after jointing, 70 grams of methyl tobuzin and 200 grams of potassium dihydrogen phosphate were mixed and sprayed with the mother to prevent and control small spot disease, once every 10 days, a total of two sprays; Before tasseling, 0 5 grams of gibberellin and 150 grams of potassium dihydrogen phosphate were used per mu, and the paternal parent was sprayed after full dissolution to promote the growth of the paternal parent and make the parental meet well during flowering. Fourth, timely harvest when the bracts are yellow and white and loose, the grains show the inherent color of the variety, and the grain milk line drops to the next 1 3 places when the harvest.

What are you**? I make seeds, there are sweet and waxy corn, you can go to the local seed distribution point to find it: Jing Nuo 208, purple flower fragrant glutinous, etc.

Bumper Producer: Agricultural Leadership Project Demonstration Party The process has developed from a bumper yield field and a bumper yield to a bumper harvest plan, and it is hoped that it will be useful to achieve a large-scale and substantial increase in production and income.

The "Bumper Producer" Approach – Although the land is still owned by each family, farmers can receive scientific and technological guidance and other help.

"Abundant yield" refers to 100,000 acres of high-yield, high-yield fertile land connected into a large area.

It is last night's high-yield plan, high-yield **, like Fengxin Agriculture's crop high-yield plan, which is a method or product that makes crops high-yield.

A field in which a large number of corn hybrid seeds are prepared is a corn seeding field. Isolation areas must be set up in corn fields to prevent foreign pollen from entering the seed production area and causing pollination mixture. Under the premise of ensuring that the father has enough pollen to meet the pollination needs of the mother, the number of rows of the mother parent should be increased as much as possible, which can improve the yield of hybrid seed production.

In order to distinguish between the father and the mother, sunflowers or sorghum can be planted at both ends of the ground and in the middle of the row as a sign of the father's bank. If the flowering period of the parent and mother is not coordinated, the seeds should be sown at the wrong time so that the flowering period of the father and mother meet. The sign of flowering encounter is that the female panicle is 2 to 3 days earlier than the male panicle pollination of the male parent.

Artificial emasculation of the female parent (if the female parent is a male sterile inbred line, artificial emasculation can be dispensed with), so that the female spike of the female inbred line receives the pollen of the male inbred line to fertilize and bear fruit, and the seeds produced on the maternal inbred line are hybrids. At the end of the pollination of the male plant, the male parent is cut off immediately, which can improve the seed production yield and avoid the mechanical mixing caused by the mixing of the male fruit ears during harvest. When the ears of the mother bank of the seed production field reach the maturity stage, the bracts and leaves of the ears turn yellow, the grains become hard, and the black layer appears at the lower end of the grains, which is the appropriate harvest period.

After harvesting, the hybrid seeds are dehydrated, dried and stored.

I don't understand what it means.

Do you want to ask how to grow corn for farming?

Attention should be paid to the following points when planting a good farming system: 1. Arranging isolation is the prerequisite for planting a good farming system.

2. Doing a good job in land preparation and fertilization is the guarantee for planting and preparing farmland. 3. Preparing parental seeds is the foundation for planting a good farm. Fourth, doing a good job of staggered sowing is the key to producing a bumper yield in the field of farming. You are welcome.

Corn is not a specialty.

It is cultivated all over the country. It is widely cultivated in tropical and temperate regions of the world and is an important cereal.

Maize is one of the most widely distributed food crops in the world, ranking third in terms of planting area after wheat and rice. Cultivation ranges from 58°N (Canada and Russia) to 40°S (South America). Corn ripens every month of the year in the world.

It's not a specialty, and corn is available in many parts of the country.

The homeland of corn is in Mexico.

The yield of corn per mu is generally 800-1200 catties, due to the difference in soil quality and other relationships, in the same area, hills and plains are twice as poor.

Generally, under the conditions of moderate fertility, the yield of fresh straw per mu of special silage corn varieties can reach tons, while the yield of practical corn per mu of ordinary seeds is roughly in tons.

In general, the yield of corn per mu in the south is in tons. Corn can be planted when the ground temperature reaches more than 10 degrees, and the growth period is generally about 90 days to 120 days.

The highest yield per mu of corn:

In 1980, the output of spring corn cultivated by Li Denghai exceeded 900 kilograms, and the output of summer corn reached 823 kilograms.

In 1984, the summer maize yield reached 950 kg;

In 1989, the yield of summer maize exceeded 1,000 kilograms, reaching kilograms.

Corn, also known as maize, corn, bud, cob. In Cantonese, it is called corn, and in Hokkien it is called panmai. It is an annual gramineous herbaceous plant, an important food crop and an important fodder**, and the highest total grain crop in the world.

Corn is the most suitable variety for industrial raw materials among the three major food crops, and it is also the grain crop with the highest degree of processing.

There are many factors that determine the yield of corn, and differences in geographical environment, varieties, cultivation management techniques, etc. may lead to the difference in corn yield. In terms of speaking, the maximum yield per mu can reach more than 900 kg. However, the large-scale corn planting has low cultivation input and poor management, and the average yield per mu in a large area is about 650 kg.

If grown at high altitudes, the yield is less than 500 kg.

Every investigation needs to be in-depth. It just so happened that I had a plot of land in the countryside with peasants living next to it. There must be some of your classmates from rural areas, and I suggest that you find more than three (too few statistics to tell the story) and come to their homes to find out

The number of family members, the number of acres of land owned, the type of crops planted, the yield, and the current year of the crop. These farmers will tell you that it is better to count for three years. Finally, do your own calculations, what is the annual income of each family?

Low per capita income?

The results of statistics can tell you whether the per capita income of farmers is related to the number of family members and laborers, what varieties are planted, whether the income of farmers has increased or decreased in the past three years, and whether life is getting better or better.

Statistical indicators" (the number of family population, the number of acres of land owned, the type of crops planted, the yield, **crop of the year**) do the line, the name of the classmate (Zhang.

Three, Lee. Fourth, Wang Er Mazi) to make a column, do a statistic **.

The yield of corn depends on the variety and management level, and the good ones are about 2,000 catties.

Yields vary greatly from region to region, and from variety to species.

Other. The yield per mu of spring maize in the three eastern provinces is generally about 500-700 kg (under the standard water content of 14 waters), the summer maize area of Huanghuaihai is generally about 600 kg, and the yield in Xinjiang is the highest up to 700-900 kg.

Three-minute seven-point management, if you want to have a high yield, you must manage the number, the yield per mu of corn is generally more than 1,000 catties, and the high yield of corn here reaches about 1,700 catties.

Household income, family population, education level, per capita amount of land, types and stubble of crops planted, yield per mu of each crop, output value per mu,

Generally about 450kg, depending on the variety of corn, the yield per mu of hybrid corn is higher, and it can reach 650kg normally
