The invention relates to a corn cultivation method, in particular to a high-yield cultivation
method of fresh-eating corn.
Most of the corn cultivation techniques in the prior art include seed selection, seed dressing,
sowing and field management, etc. Generally, high-yield and high-quality hybrid varieties
are selected: high-yield and high-quality hybrid varieties with strong disease resistance,
moderate growth period and compact plants are selected. Sowing: when the ground
temperature is stable through 5-7°C, it is the suitable sowing time for corn.
The methods of seed selection and seed dressing are as follows: select seeds with high
purity, good clarity and full grains, sun them for 2-3 days before sowing, soak them in 0.1%
potassium dihydrogen phosphate solution or warm water at 50-55°C for 2-3 hours, pick
them up, filter them out, and keep them in a warm place above 20°C to germinate until they
can be sown.
The methods of sowing and field management are as follows. Fertilization, corn
fertilization focuses on base fertilizer and bract-tapping fertilizer, and skillfully applying
seedling fertilizer and jointing fertilizer according to seedlings. Apply 20 kg of compound
fertilizer with N-P-K content of 15-15-15 as seed fertilizer per mu, and apply 50-80 Kg of
urea as topdressing atjointing stage. When a defertilized and premature aging plot is found,
150 grams of potassium dihydrogen phosphate and 500 grams of urea can be sprayed as
appropriate per mu. However, with the current cultivation method, the corn yield is limited.
In order to solve the problems in the prior art, the invention provides a high-yield
cultivation method of fresh-eating corn. By utilizing the technical scheme of the invention,
the quality, the number of fresh ears and the yield of corn can be remarkably improved,
and the input cost can be remarkably saved and the economic benefit can be improved.
In order to achieve the purpose of the invention, the technical scheme adopted by the
invention is as follows.
A high-yield cultivation method of fresh-eating corn comprises the following steps.
(1) Select high-quality fresh-eating corn varieties.
(2) Isolated planting: adopt space isolation and/or time isolation according to the situation
of planting corn around.
(3) Seed selection and coating: before sowing, screen the quality of the variety seeds,
classify the variety seeds according to size, and then coat the seeds.
(4) Single seed sowing in large and small rows: sow in large and small rows, determine
plant spacing according to the appropriate density of varieties, and adopt single seed
sowing.
(5) Application of controlled release fertilizer: apply 40-50 kg of controlled release
fertilizer to each mu of land, and sow the fertilizer and seeds in different rows with a
distance of 5-8 cm.
(6) Field management: conduct intertillage and weeding, conduct intertillage twice. Water
supply should be ensured from heading and flowering to grain filling stage. Spray potassium dihydrogen phosphate solution on leaves during pollination and grain filling stage. After pollination, cut off all tassels. Pay attention to pest control.
(7) Timely harvest: fresh-eating corn is harvested 20-25 days after pollination.
Further, the spatial isolation in the step (2) is at least 300-500 m away from adjacent corn
varieties,
Further, the time isolation in the step (2) is the sowing interval of 15-20 days in spring and
-10 days in summer.
Further, step (3) of seed selection and coating is to classify the seeds and coat them with
corn seed coating agent, with the dosage of 130-150 g/lOOKg seeds.
Further, in the step (4) of sowing, the large row is 80 cm, the small row is 30 cm, and the
plant spacing is 20-28 cm.
Further, the controlled release fertilizer in step (5) is a water-soluble controlled release
fertilizer with the formula of N : P : K being 25 : 10 : 10 and adding trace element zinc.
Further, the intertillage of step (6) is to conduct the first shallow intertillage at 5-7 leaves
after the seedling, remove the tillers in time, and conduct the second intertillage at jointing
stage.
Further, in the step (6), when the number of insects is small, adopt an interlaced
emasculation method. Use biological pesticides to control serious pests.
Further, the step (7) is to harvest in the morning and evening.
The invention has the advantages and technical effects that by adopting the coating method
of the invention, the germination rate, seedling uniformity, strong seedlings and flourishing
root system can be improved, meanwhile, needle worms, planthoppers and the like can be
prevented and the incidence rate of corn rough dwarf disease can be reduced.
Adopt the controlled release fertilizer technology for sowing and fertilization at the same
time to reduce labor. High temperature and heavy rainfall in the main growing season of
corn are easy to cause fertilizer decomposition and loss. Using controlled release fertilizer
can effectively reduce nutrient loss, realize accurate fertilization and ensure no fertilizer
loss in the later period.
The method has simple operation steps and is suitable for reference and use by professional
planters or ordinary workers. It not only ensures the quality, number of fresh ears and yield
of fresh-eating corn, but also significantly saves the input cost and improves the economic
benefits.
In order to make the object, technical scheme and advantages of the present invention
clearer, the embodiments of the present invention will be further described in detail below.
The high-yield cultivation method of fresh-eating corn specifically comprises the following
steps: selecting high-quality fresh-eating corn hybrids, isolated planting, seed selection and
coating, sowing single seeds in large and small rows, applying controlled release fertilizer,
field management and timely harvesting.
1. The method for selecting high-quality fresh-eating corn hybrids is specifically as
follows. Select high-quality fresh-eating corn hybrids.
The specific selection method is as follows. Select suitable varieties according to the
perennial accumulated temperature, light and moisture in the specific geographical
location. According to the soil fertility and topography of specific plots, high-yield and
fertilizer-liking varieties can be selected for plots with high geography, stable and barren
tolerant varieties can be selected for plots with low soil fertility, and early-maturing
varieties can be selected for depressions. According to the perennial occurrence of diseases
and insect pests in specific plots, for example, for plots with serious occurrence of rough
dwarf disease, varieties resistant to rough dwarf disease should be selected.
2. The specific method of isolated planting is to adopt space isolation or time isolation
according to the situation of planting corn around to ensure the quality of corn.
The space isolation is generally 500 m away from the adjacent corn varieties, and the time
isolation is generally the sowing interval of 15-20 days in spring and 5-10 days in summer.
3. The specific method of variety seed selection and coating is as follows. Before sowing,
screen the quality of variety seeds. Use 7mm round-hole seeds to screen the seeds, divide
the seeds into two types, and then coat the seeds. Choose Syngenta Ruisheng corn coating
agent, the dosage is 150 g/100Kg seeds.
The seed selection and coating technology is to classify seeds according to size, and use
Syngenta Ruisheng corn seed coating agent for coating. It is highly safe to the environment
and can effectively prevent and control various soil-bome and seed-borne diseases and
pests in early corn. It provides long-term protection to corn, and at the same time can
obviously promote corn growth and exert the potential of increasing yield.
4. The specific method of single seed sowing in large and small rows: when sowing, use
large and small rows, 80 cm for large rows and 30 cm for small rows, determine the plant
spacing according to the appropriate density of the variety, and use single seed sowing to
save the operation process of thinning after emergence.
5. The specific method of applying controlled release fertilizer is as follows: apply 50 kg
of controlled release fertilizer per mu of land, sow the fertilizer and seeds in different rows
with a distance of 5-8 cm.
The controlled release fertilizer is a water-soluble controlled release fertilizer with the
formula of N : P : K of 25 : 10: 10, controlled release of 13 N and addition of trace element
zinc.
6. The specific methods of field management are as follows. Conduct intertillage and
weeding according to the actual situation of the field. Conduct intertillage twice according
to the actual situation. Generally, conduct the first shallow intertillage at 5-7 leaves after
the seedling, remove the tillers in time, and conduct the second intertillage and weeding at
jointing stage. Water supply should be ensured from heading and flowering to grain filling
stage. Spray potassium dihydrogen phosphate solution on leaves during pollination and
grain filling stage. After pollination, cut off all tassels.
Pay attention to the prevention and control of diseases and insect pests, mainly corn borer
and aphid. When the number of insects is small, artificial control is the main method, and
interlaced castration can obviously reduce the number of insects. When the pests are
serious, use biological pesticides such as pyrethroid pesticides or bt emulsion to control
them, and ban high toxic pesticides such as dimethoate and 1605.
7. The specific method of timely harvesting is that fresh-eating corn should be harvested
-25 days after pollination, not too late or too early. It is best to harvest it in the morning
and evening, transport it at night and keep it fresh. After harvest, corn should be sold in
time within 24 hours or sent to the processing plant for refrigeration or processing to
prevent deterioration.
The above embodiments are only used to illustrate the technical scheme of the present
invention, but not to limit it. Although the invention has been described in detail with
reference to the aforementioned embodiments, it is still possible for ordinary technicians
in the field to modify the technical solutions described in the aforementioned embodiments,
or to replace some of the technical features equally. However, these modifications or
substitutions do not make the essence of the corresponding technical scheme deviate from
the spirit and scope of the technical scheme claimed by the present invention.
