Ⅰ. Product Details

Variety Characteristics

White Sweet Waxy Corn is a premium dual-purpose corn variety combining the sweetness of sweet corn and the glutinous texture of waxy corn. It is an early-maturing variety with a growth cycle of about 80-90 days. Each ear weighs 200-300g, with 14-16 rows of kernels, featuring plump grains and excellent commercial quality.

Quality Advantages

• Kernels are snow-white, full and translucent with thin skin and thick flesh. Boiled kernels are soft and glutinous with rich sweetness, chewing-resistant and residue-free.
• Rich in amylopectin (nearly 100%), dietary fiber, vitamins B1, B2 and minerals such as potassium and magnesium. It has low glycemic index and is suitable for people of all ages.
• Good fresh-keeping performance: Harvested fresh ears can be stored at 0-5℃ for 7-10 days, and can be processed into quick-frozen corn, corn juice, corn starch, etc., with high processing utilization rate.

High-Yield Characteristics

Plants are compact with strong lodging resistance, growing to a height of 180-220cm. Each plant bears 1-2 ears with high fruiting rate. The yield of fresh ears per mu can reach 1200-1500kg. It has wide adaptability, suitable for planting in plains, hills and other regions, with strong disease resistance and simple management.

Application Scenarios

• Fresh food market: As a high-grade fresh corn, it is popular in supermarkets, farmers’ markets and catering industry, with high unit price and good economic benefits.
• Processing industry: Suitable for processing into quick-frozen waxy corn, canned corn, corn paste, etc., with stable supply and demand and broad market prospects.
• Home garden planting: Short growth cycle, suitable for intercropping and relay cropping, meeting the family’s demand for fresh corn.

Selection & Storage Suggestions

• Selection skills: Choose fresh ears with green husks, plump kernels, tight arrangement and milky white color. The corn silk should be moist and not dry, with no insect eyes or mold spots.
• Storage method: Fresh ears can be stored in a refrigerator at 0-5℃ for 7-10 days. For long-term storage, remove husks, blanch in boiling water for 3-5 minutes, cool quickly and freeze, which can be stored for 6-8 months.

Ⅱ. Planting Methods

Planting Preparation

1. Soil Selection

White Sweet Waxy Corn prefers loose, fertile, well-drained loam or sandy loam with pH value between 6.0-7.5. Avoid continuous cropping with other corn varieties to prevent cross-pollination affecting quality. Deep plow the land 25-30cm before planting, remove weeds and apply base fertilizer: 2000-3000kg of decomposed farmyard manure, 40kg of compound fertilizer and 20kg of phosphate fertilizer per mu. Mix evenly and make ridges with width of 60-70cm.

2. Seed Treatment

• Seed selection: Choose full, disease-free seeds with high germination rate, with seed consumption of about 1.5-2kg per mu.
• Seed soaking and germination: Soak seeds in 25-30℃ warm water for 12-24 hours, then place them in a warm environment of 28-30℃ for germination. Rinse with water once a day and sow when seeds show white buds of 1-2mm.

Sowing & Planting

1. Sowing Time

• Spring sowing: When the soil temperature stabilizes above 10℃ (late March to early April in southern China, mid-April to early May in northern China);
• Summer sowing: Can be sown in late June to early July, avoiding high temperature and drought during flowering and pollination;
• Autumn sowing: In southern China, it can be sown in late July to early August, and harvested before frost.

2. Sowing Methods

• Direct seeding: Adopt ridge sowing with row spacing of 60-70cm and plant spacing of 25-30cm. Sow 2-3 seeds per hole, cover with 3-5cm fine soil and water thoroughly. Thin seedlings after emergence, leaving 1 strong seedling per hole.
• Seedling raising and transplanting: For early maturing, raise seedlings in nutrition bowls 20-30 days in advance, transplant when seedlings have 3-4 leaves, and water thoroughly after transplanting to ensure survival.

3. Isolation Planting

To prevent cross-pollination with ordinary corn and sweet corn affecting glutinous quality, isolation measures should be taken: spatial isolation (distance from other corn varieties more than 300m) or temporal isolation (sowing time staggered by more than 20 days).

Field Management

1. Seedling Management

• Thinning and seedling supplementation: Thin seedlings at 2-3 leaves, leave strong and remove weak; supplement seedlings in time for missing ridges and plants to ensure full stand.
• Cultivation and weeding: Cultivate shallowly at seedling stage to loosen soil and remove weeds, and cultivate deeply at jointing stage to promote root growth and prevent lodging.

2. Water Management

• Seedling stage: Keep soil moist, avoid drought and waterlogging;
• Jointing and heading stage: Critical period for water demand, water in time when soil moisture is insufficient, ensure adequate water supply during tasseling and silking;
• Filling stage: Maintain proper soil moisture to promote kernel plumpness, reduce watering 7-10 days before harvest.

3. Fertilizer Management

• Seedling fertilizer: Apply 8-10kg of urea per mu at 3-4 leaves to promote seedling growth;
• Jointing fertilizer: Apply 15-20kg of compound fertilizer per mu at jointing stage to promote stalk thickening;
• Panicle fertilizer: Apply 20-25kg of compound fertilizer + 10kg of potassium fertilizer per mu at big trumpet stage (10-12 leaves) to ensure panicle development and kernel plumpness.

4. Pest Control

• Underground pests (grubs, wireworms): Mix seeds with insecticides before sowing, or apply granular pesticides in planting holes;
• Armyworm and corn borer: Use 2.5% deltamethrin emulsifiable concentrate 2000x solution or Bt emulsion for spray control at seedling and jointing stages;
• Rust and leaf spot: Spray with 25% triadimefon wettable powder 1000x solution or 50% carbendazim 800x solution for prevention and control.

Harvesting

• Harvest time: Harvest 20-25 days after silking when kernels are plump, milk stage (kernels contain milk juice when squeezed), husks turn from green to light green;
• Harvesting method: Harvest in the morning or evening, cut off ears with sharp knives, retain 2-3cm stalks, avoid damaging kernels, and process or sell in time after harvest;
• Processing: Fresh ears can be sold directly, or processed into quick-frozen products after husking, blanching and cooling.
