New technology for planting corn in northern Xinjiang, new technology for high yield corn planting

The Xinjiang Academy of Agricultural Sciences should have promoted it.

2. What varieties of Xinjiang corn are good 1, planting Xinjiang corn is generally better to choose Xinyu No. 10, Xinyu No. 13, Xinyu No. 29 and other corn varieties. 2. Xinyu No. 10 seedlings to maturity, it takes 102-103 days in northern Xinjiang, 82-90 days in southern Xinjiang, the number of leaves of the whole plant is 13-14, and the average height of each plant is about 180-230 cm. 3. Xinyu No. 13 is an early-maturing high-yield grain feed and high-starch corn hybrid, its seedling leaf color is dark green, the leaf sheath and leaf edge color are purple, the first leaf shape is oval, the plant is flattened, the average height of each plant is about 289 cm, and the total number of leaves is about 20-22 Chang cherry.

4. Xinyu 29 is an early-maturing high-starch corn hybrid variety, which can be replanted after wheat harvest in southern Xinjiang, and can also be sown in cold and cool areas in northern Xinjiang, with a growth period of 88 days. This variety is highly resistant to powdery mildew, silk smut and bacterial wilt, and has good green retention and lodging resistance.

In the planting of corn, in order to obtain the ideal yield and income, it is necessary to do a good job in the management of all links, start from the details, and do not ignore any management link, in order to ensure the high yield and stable yield of corn.

To have a high yield of corn, it is necessary to choose varieties with higher yield and strong resistance to stress, it is best to choose Nongda 108, Denghai 9, Zhengdan 958, Ludan 981, etc., before sowing, we must select seeds, remove deflated grains, small grains, unqualified grains, etc. After the seeds are selected, the germination rate can be tested 15 days before sowing, and then the seeds can be spread out and dried in a dry sunny place 3-5 days before sowing.

The planting time and temperature control is also very critical, when the spring temperature reaches more than 12 °C, it can be sown, Pingba and shallow hill areas are generally sown in mid to early March, and deep hills, middle and low mountainous areas are suitable for sowing seedlings in late March and early April, so as to shorten the symbiosis period of wheat and jade, and cultivate strong seedlings.

In order to achieve a high yield of corn, it is provided with humus-rich and loose and breathable sandy loam soil, and then applied rotted chicken and duck manure to the soil surface, and then ploughed the land to make it more fertile and soft, and then the corn seeds can be sown on the soil surface to promote its vigorous growth.

Corn needs sufficient nutrients in the growth process, when breeding corn, it is necessary to apply 2-3 times of nitrogen, phosphorus and potassium compound fertilizer for it after the plant emerges, so that the growth rate of corn is accelerated, and during the corn fruiting period, it is necessary to spray potassium dihydrogen phosphate on its leaves, so that the yield of the plant is increased.

Corn likes water, but is not tolerant to waterlogging, when breeding corn, you need to adjust the frequency of watering according to the weather conditions, in the rainy season, you need to dig a drainage ditch for corn, and drain the water in the soil in time to avoid corn water decay, and when the environment is relatively dry, you need to water the corn every three days.

Taking the No. 8 variety of Agricultural Science and Technology selected and bred by the team of Professor Wu Quanming of Northwest A&F University after 6 years of repeated experiments, the yield per mu of general planting is about 1000, but under high-yield cultivation, the yield per mu is likely to exceed 1200 kg. In addition, under the conditions of normal planting and high-yield planting, the yield gap per mu of Shaanxi 609 was as high as 500 kg. Although the region is different, the yield is not much, but the difference in the yield of corn is mainly in the management, simply rely on the sky to eat, desperately spray all kinds of pesticides to no avail, the yield will definitely not go up, but pay attention to these points, the yield of corn will naturally rise.

Sowing problems. 1. Sowing period.

High-yield planting has strict requirements for the sowing period, under normal circumstances, each planting area has the best sowing time, taking Henan Province as an example, late April every year is a better choice, not too early, not too late.

2. Seed selection (high-yielding varieties).

Some varieties themselves can not reach the yield of 1200 kilograms, no matter how much cultivation is useless, so we take the No. 8 Agricultural Science University of Xinong University as an example, before sowing, the seeds should be screened first, the size of the fullness should be the same or similar, before sowing, it is best to carry out drying treatment, it generally takes 2-3 days, during the drying period, turn it over when there is nothing to do.

3. Deep and shallow species.

Shallow planting can be done in wetter climates, and deep planting is done in drier climates.

4. Planting density.

The planting density is about 10,000 plants per hectare, and too loose or too dense is not conducive to achieving a high yield of more than 2,400 catties of corn.

The high-yield corn variety Longgao L2 is known for its yield per mu of grain (667) and iron resistance.

In 2002, the average yield per hectare of Longgao L2 production test was kilograms. [1]

Longgao L2 was bred by the High Yield Breeding Room of the Maize Research Institute of Heilongjiang Academy of Agricultural Sciences.

It can't be rolled out nationwide, but it can be rolled out in the Northeast. Xinjiang has a vast land and sparse population, and generally the Xinjiang Construction Corps uniformly grows crops, and the area planted by each household is very large, and the land of each household is concentrated together. Therefore, it is possible that a large harvester will still be a family's land in the field for a day.

Xinjiang's current agricultural development is inseparable from the efforts of generations of young people in the border areas. After the liberation of Xinjiang in 1949, Xinjiang was mainly based on nomadic agriculture at that time, and people lived in seclusion after water and grass, the production mode was very backward, and the agricultural output was also very low. <>

In 1950, the People's Liberation Army stationed in Xinjiang began to invest in production and construction, and achieved self-sufficiency in grain and vegetables that year. In 1953, the army divided into two parts, one for national defense and the other for production. In 1954, some of the troops who came to Xinjiang to defend the border areas were transferred to other jobs on the spot, and this is the origin of the Xinjiang Construction Corps.

Since then, Xinjiang has undergone earth-shaking changes, the desert has become an oasis, and over the past 60 years, generation after generation of XPCC members have taken root in the fertile soil of Xinjiang, creating one miracle after another. Xinjiang grows cotton according to local conditions, and it is exported overseas. Due to the special geographical location of Xinjiang, Xinjiang is a high-quality crop or a fruit and has won a lot of praise.

Xinjiang develops Xinjiang's special agricultural products according to local conditions, many machinery and agricultural tools are with local characteristics, and are the crystallization of the wisdom of the Xinjiang Corps, so they can be used for reference, but they cannot be copied all, and the terrain and agricultural planning of each place are different.

Yes, because this kind of machinery harvests crops quickly and can help farmers save a lot of time and energy, and it is worth promoting.

Unlikely. The topography of each province is completely different, especially in mountainous areas, it is difficult to generalize, and this must be based on different strategies.

There is no need to promote the whole country, because the rest of the place will be reserved for real estate. There aren't many of these farms and they can't be used, so there's really no need.
