Sweet corn is high-yield with skill! Sweet corn high-yield planting technology
Corn varieties have different tastes. At present, edible corn is the most popular Sweet Corn. It has the characteristics of good taste, sweet taste and juicy and crisp, which is very popular among consumers. Moreover, sweet corn has wide adaptability and high planting efficiency. Let's talk about the high-yield planting technology of sweet corn.
1, variety selection
The varieties with wide sales, high yield, high quality and strong resistance can be managed well and the yield per mu can reach more than 2000 kg.
2, sowing
Spring is in the middle and late March, and autumn is in early July.
3, nursery
Use fertile vegetable gardens for seedling beds (such as directly opening seedbeds in Datian, mixing 10 kg of 3 15 compound fertilizers on 20 square beds, improving the fertility of the field seedbed), and opening the drainage ditch.
40 pieces of 100-hole seedling tray per acre are spread on a good seedbed. In the early spring, the seedlings cover the film insulation, and the summer and autumn seedlings cover the sunscreen with a sunshade net. After the emergence of 2 leaves, the sunshade net is removed.
4, transplanting Daejeon
(1) Land selection conditions
Choose water and dry fields with high soil fertility and convenient irrigation and drainage.
(2) Fine land preparation
Sorghum deep ditch, deep plow 20cm, after flattening, according to the width of the face is 100cm, the width of the ditch is 30cm, the depth of the ditch is 20-30cm, and the coffin is formed into fine granules. The second production can be carried out without tillage.
(3) Applying sufficient base fertilizer
Mu with fermented farmyard manure 3000-4000 kg mixed superphosphate 100 kg, potassium chloride 20 kg or imported three 15 compound fertilizer 20 kg in the crepe as the base fertilizer applied to the planting ditch and cover the thin soil.
(4) Transplanting
1. Spray 150 ml of acetochlor herbicide herbicide 3 days before transplanting.
2. Transplanting density: large row spacing 80cm, small row spacing 50cm, plant spacing 25-30cm.
3. Transplanting time and planting method: When the seedlings have 4 leaves, they can be planted in a direction (the leaves should be perpendicular to the rows), and the full water can be ensured after planting the water.
5, field management
(1) Fertilization
1. Lifting seedling fertilizer: After 5 days of planting, use water (lean gas water) 20 ton + urea 5 kg to promote root growth.
2, the allocation of fertilizer: in the 8-9 leaves combined with cultivating weeding, loosening soil, soil fertilization of urea, potassium fertilizer each 25-30 kg.
3, attacking the fat: in the big bell mouth period (about 12 leaves) acres of urea, potassium fertilizer 20-25 kg, or three 15 compound fertilizer 20-25 kg, weeding loose soil, clay pot fertilization.
4, grouting fertilizer: in the loose powder period according to the seedlings, the application of 5-10 kg of urea to extend the green leaf functional period.
5, skillfully apply foliar fertilizer: spray 6 Guoguang corn dwarf leaf noodle fertilizer on 6-9 leaf acre, spray 1000 times imported boron fertilizer +0.4% potassium dihydrogen phosphate before flowering.
(2) Water management
In the dry season, the water holding capacity of the soil is up to 70%, and the horse water is irrigated once during the flowering period.
6, pest control
(1) Seedling period: mainly control pests such as tigers, crickets and green worms.
(2) The allocation and the ear-forming stage: 1000-1500 times of the use of corn glutinous rice can be used for the prevention and control of corn gluten or 800 times 2-3 times of 2% gamma salt. Jinggangmycin is selected for the control of sheath blight, and 800-fold or 800-fold chlorothalonil is selected from the corn mold spot disease.
(3) Aphids are harmful during the flowering stage of the ear, and anti-Puwei or imidacloprid pesticides (such as Dagongchen, Jindadi, etc.) can be used, and pesticides are prohibited for 20 days before harvest.
Sweet corn planting management is not difficult, mainly to do a good job in pest control. I hope the above will help you. If you want to know more about agricultural technology, please pay attention to the Hui Nong School!
