Many people like sticky corn, how to prepare the land carefully when planting?

<>1. The purpose of land preparation

To increase the yield of maize, it is stipulated that the soil layer is thick, the soil is loose, the size and porosity account for a moderate proportion, wet but not sticky, dry but not hard enough, and the elements of water, fertilizer and gas and heat are in harmony with each other, so as to facilitate the growth and development of rhizomes. In addition, the content of available nutrients in the soil layer is high, and 80 ** of the nutrients required by corn are in the soil, and only 20 40** are in chemical fertilizers. Therefore, land preparation is to make the soil layer virtual and solid, which is conducive to soil water, fertilizer and warmth.

Creating more soil colloids and making the soil layer properly loose is conducive to the generation of soil porosity, water and gas movement, and the improvement of soil microbial strain theme activities and soil physical and chemical properties, so as to build a better soil natural environment for the growth and development of maize.

2. Technicality of land preparation

After the previous stubble is obtained, it is necessary to carry out comprehensive utilization of straw and deep ploughing in autumn. The comprehensive utilization of straw can improve the composition of soil organic matter and improve the cultivated land. Autumn deep ploughing, can make the soil have a longer maturation time, the same can improve soil fertilizer efficiency, if it is waterland, after autumn ploughing, you can fill the bottom before freezing, so that the soil moves down, according to the freeze-thaw cycle to replace the mature soil, in early spring to carry out the top rake rake.

Sometimes it is too late to carry out autumn deep ploughing, so it is necessary to strive for early ploughing in the second year, and follow the ploughing to avoid running moisture.

Late ploughing not only has a shorter soil maturation time, but also the temperature rises rapidly in spring, and the wind is strong and the moisture runaway is more serious, which is harmful to planting and budding. If it is planted in dry land, it should be repeatedly carried out in spring to ensure that the soil is crushed without slack, the top is virtual and the bottom is solid, the ground is leveled, and the ventilation and moisture caused by the block should be reduced. A thin layer of dry soil is produced on the surface after raking, which can reduce the volatilization of soil moisture in the next layer and facilitate germination.

Turning, raking, raking:

This kind of method is generally carried out in autumn, with mechanical equipment to plough the deep depth can reach 18-22 cm, after turning the rake 2-3 times, to level the broken clods. If the machine leads the mouldboard plough to carry out the harrowing, the surface soil can be rotated left and right, but the solid soil is not very good and fast, and it is not suitable for every year, and it can be once every 3-5 years.

It is necessary to vigorously advocate autumn ploughing and autumn raking, which is conducive to loosening the soil, burying stubble, eliminating weeds, gas exchange in the soil and the growth and development of soil microbial strains, and improving the physical and chemical characteristics of the soil. When there is a premise, it can also be combined with the ground to apply organic fertilizer, base fertilizer and chemical fertilizer at one time. Autumn land preparation won the agricultural work for the next spring, which is conducive to accepting the rain, dew and frost in autumn, winter and early spring, and improving the ability to tolerate drought.

Cultivator, stubble destroyer, land preparation:

This kind of method is generally in the autumn without stubble machine to prepare the land to the spring of the next year to carry out, according to the micro-tiller stubble machine at the same time loose soil, can be applied in the original ditch into the base fertilizer or organic fertilizer, the ground pest and disease is more serious land can also release the treasure and other fertilizers.

It is best to use mechanical equipment with small horsepower, which is suitable for individual work, so that the coordination ability and control are strong. However, spring land preparation usually scatters moisture, which increases the pressure of spring work, and is not conducive to the generation of solid sand soil structure, which is easy to cause soil weathering, and will harm the budding when the spring drought is heavier.

For the planting of clay corn, pay attention to enhancing the fertility of the soil when preparing the land, and try to choose those nutrient-rich soils.

1. Choose varieties: There are many varieties of sticky corn, and hybrids suitable for local natural conditions and cultivation conditions are better. Some landraces are of particularly good quality and can be planted optionally.

Pay attention to the requirements of market habits in the type of variety, pay attention to the combination of early, middle and late varieties, extend the first time, and meet the needs of the market and processing plants.

2. Phased sowing: In order to meet the needs of the market, raw material processing, spring sowing, summer sowing, autumn sowing, cooking as fresh fruit ears, and trying to harvest fruits in the off-season or early season to obtain higher economic benefits. Therefore, the cultivation of sticky corn should be based on market demand, and follow the principles of multi-stage sowing, promotion and promotion, and balanced marketing.

After the first sowing, you can sow a batch every 7 10 days according to the market demand, and the latest sowing date can ensure that the temperature of the harvest period is above 18. Generally, the last batch of sowing dates in Jiangsu, Zhejiang and Shanghai can be mastered at the end of July and early August, and the listing time is late October.

3. Reasonable planting density: Reasonable planting density is related to sticky corn varieties, fertilizers and climatic conditions. For example, late-maturing varieties have a long growth period, tall plants, lush stems and leaves, and strong production capacity per plant, so they should be planted appropriately; On the contrary, the dwarf plants of early-maturing varieties should be planted appropriately and densely.

In the case of high fertility, it can be properly densely planted; In the case of poor fertility, in order to ensure that each plant has sufficient soil nutrients and water, it should be planted properly.

4. Scientific fertilization: organic fertilizer is applied as base fertilizer, and it is generally recommended to apply 2500 3000 kg of fully decomposed high-quality manure per mu of cultivation. The application method should be determined according to the amount of basal fertilizer, when the quantity is sufficient, it can be used to spread and then plough into the soil.

If the quantity is small, it can be concentrated in the sowing furrow, which is more economical and has a good effect.

<>1. Land preparation treatment: Corn should be treated before planting, and the deep turning of the finger plot should ensure that the soil is loose. At the same time, it is necessary to pick out the soil clods and stones, otherwise it will affect the laughter and seedlings.

2. Planting into the soil: Corn is usually sown by hole sowing. Pay attention to the density of planting, usually about 5,000 plants per acre, not too dense, otherwise the silver base will not be well ventilated, light transmitted, will affect the growth.

The planting depth is about 35 centimeters deep. After planting, cover the soil in time and moisturize.

3. Later management: When the corn seedlings grow, the seedlings should be thinned and replenished in time. It is also necessary to water and moisturize properly, its drought tolerance is limited, and the dry soil will hinder the germination of young seedlings.

In addition, it is necessary to supplement fertilizer in time during the peak growing season, and the better quality corn will be produced in the later stage when the nutrients are sufficient.

4. Insect and disease prevention: In addition to strengthening management, we should also pay attention to the prevention and control of pests and diseases. When there is a lot of rain, it is easy to be infected with pests and diseases, so it is necessary to spray pesticides in time to avoid hindering growth.

5. The planting time of sticky corn in the north should be selected in spring, probably between the valley rain and the middle of May, during which the climate temperature is basically stable, and the seeds can germinate faster after planting, and the corn seedlings can also grow vigorously. Usually it will be available around October in the fall.

<> sticky corn can be planted about 3000-3500 trees per acre, and it will generally be planted in accordance with the planting method of dense planting, row spacing of 1m, nest spacing, and a nest of two plants. Spring waxy corn is mulched with plastic film, 5-7 days earlier than conventional corn sowing, generally at the end of February or early March, and transplanting is completed at the end of March. Waxy maize sowing varieties should be selected with short growth period, wide adaptability, strong disease resistance, beautiful ear shape, and good taste of fresh fruit ears.

1. How many sticky corn are planted in one acre of land

1. One acre of sticky corn can be milled about 3000-3500 or so, and the planting method of one nest and two plants is generally taken according to the dense planting row spacing of 1m and the nest spacing. However, due to the differences in planting habits in each region, the row spacing and plant spacing will also be different, and the number of trees planted will be different.

2. Spring waxy corn can generally be covered with plastic film to raise seedlings, which is about 5-7 days earlier than conventional corn sowing. Generally, planting is carried out at the end of February or early March, and transplanting can be completed at the end of MarchAutumn waxy corn is generally sown in late July, and the late sowing time can not exceed mid-August, and the sowing in high-altitude areas can be advanced to mid-July.

3. When planting waxy corn, you can generally choose varieties with short growth period, wide adaptability, strong disease resistance, beautiful ear shape, and good taste of fresh fruit ears, such as Yu Nuo series, Su Yu series, Jingke Nuo series, etc.

Second, the planting method of sticky corn

1. The whole place is excited.

1) When planting sticky corn, be sure to prepare the land in advance, and then choose a plot that is convenient for drainage, irrigation, sufficient sunlight, and deep soil layer for planting.

2) First clean up the weeds and debris in the plot, and then turn it deep 1 time, which can ensure that the soil is fertile.

3) In order to make the corn grow vigorously in the later stage, sufficient base fertilizer can be applied in the plot, and generally the rotted farmhouse fertilizer can be used as the base fertilizer, so as to ensure its vigorous growth.

2. Plant into the soil.

1) Corn is generally sown by hole sowing, and the sowing density must be controlled, and about 5,000 plants need to be planted on 1 acre of land.

2) Pay attention not to sow too densely, otherwise the seedlings will not be well ventilated, and it will also affect the light transmittance, which is not conducive to the growth of the later stage.

3) Generally dig 3-5cm holes, put 2-3 seeds in each hole, after planting must be covered with soil and moisturized, the general environment is suitable for seedlings will emerge soon.

3. Seedlings at the right time.

1) Corn seedlings are generally carried out when there are 2 leaves and 1 heart, and the seedlings that are too dense must be thinned in time, and the seedlings must be replenished.

2) Be sure to ensure that 1 strong seedling is left in 1 hole, and corn seedlings that are too dense or too sparse will affect the yield.

4. Post-management.

1) The demand for nutrients in corn seedlings during the growth period is relatively large, so reasonable topdressing must be carried out to ensure that the nutrients are sufficient.

2) Fertilizer can be selected according to the growth stage, and only reasonable top dressing can ensure vigorous growth.

(3) In addition, we should also pay attention to pest control, especially when there is a lot of rain, we must spray drugs in advance for prevention, so that the probability of infection with pests and diseases will reduce the yield.

To buy good quality seeds, sow in the spring or early summer, this time of the feast is auspicious when the climate is mild, rainy, suitable for corn growth, before planting the soil needs to be turned, enhance the grip of drainage and air permeability.

The interval should be controlled, and the appropriate amount of fertilization should also be done, and not excessive fertilization, which will lead to necrosis of corn seeds.

<>1. Planting time. Planting sticky corn is usually carried out in spring, probably between the grain rain and May, when the climate temperature is basically stable, it is easy to manage after planting, the seeds can germinate faster, and the corn seedlings can also be sent to grow better. In general, if you plant and manage it properly, you can harvest it in autumn around October.

2. Land preparation treatment. When planting sticky corn, it is necessary to prepare the land in advance, and choose plots that are easy to drain, irrigate, have sufficient sunlight and deep soil layer for sowing. First clean up the weeds and debris in the plot and turn it deep once to ensure that the soil is fertile.

In order to promote vigorous growth in the later stage, it is best to apply sufficient base fertilizer in the dust ears of the plot, and use well-rotted farmhouse fertilizer as base fertilizer to ensure its vigorous growth.

3. Plant into the soil. Corn is generally sown by the method of hole sowing, must control the density of sowing, generally an acre of land needs to plant about 5000 plants, can not be sown too dense, otherwise the seedlings can not be well ventilated, but also affect the light transmittance, is not conducive to the growth of the later stage. Generally, dig 3-5 cm holes, put two or three seeds in each hole, cover the soil and moisturize in time after planting, and the seedlings will emerge soon if the environment is suitable.

4. Seedlings at the right time. Corn seedlings are generally carried out when the two leaves are one heart, and the seedlings that are too dense are thinned in time, and the seedlings are also replenished to ensure that a strong seedling is left in a hole, and the corn seedlings are too dense or too sparse will affect the yield.

5. Post-management. Corn seedlings have a large demand for nutrients during the growth period, and they need to be reasonably topdressed to ensure that the nutrients are sufficient. Fertilizer is selected according to the growth stage, and reasonable top dressing can ensure vigorous growth.

In addition, it is also necessary to pay attention to the prevention and control of pests and diseases, especially when there is a lot of rain, it is recommended to spray drugs in advance for prevention, infection with pests and diseases will reduce the yield.
