One, choose the best varieties
Fruit corn is mainly young ears as fruit, vegetables, fresh food market or canned products, it is appropriate to choose a strong adaptability, cob uniformity, good quality, high purity varieties, and pay attention to the varieties of early, medium and late maturing with each other, a steady stream of raw materials for the market and processing plants. Selection of good varieties is very critical to the crop yield, commercialization has a great role. Such as Lima 1, Lima 2, etc., these varieties of high sweetness, good quality, can be planted. The annual nitrogen, phosphorus and potassium demand ratio is about: 1: 0.5: 1.2. Compound fertilizer (16-19-10) 35kg or (15-15-15) 30kg. corn's fertilizer law is the seedling period accounted for 2% of the total amount of fertilizer fertilizer for the entire reproductive period, 85% of the spike period, 13% of the grain period.

Variety origin: Parent Beijing Glutinous 6, from Zhongguo Glutinous 1; Parent BN2, from Purple Glutinous 3.
Characteristics: In the southwest region, the period from seedling to harvest is about 85 days, which is comparable to the control Yu Nuosuo 7. It is widely adapted, with strong resistance to disease and stress. Seedling leaf sheaths are purple, leaf blades are dark green, leaf margins are green, anthers are green, and glumes are pink. The plant is semi-compact, with a plant height of 250 cm, spike height of 95 cm-115 cm, and the number of leaves of the adult plant is 19. The filaments are pink, and the spike is long conical, with a length of 19 cm, a number of rows of 14, a 100-grain weight (fresh kernels) of 36.1 g, white seeds, and a white rachis. In the southwest regional test in the average collapse (folding) rate of 6.9%.
By the Sichuan Academy of Agricultural Sciences Plant Protection Research Institute two years inoculation identification, medium resistance to large spot disease and blight, susceptible to small spot disease, Silky Spike Disease and corn borer, highly susceptible to stem rot. By the Southwest Fresh Glutinous Corn Regional Trial Organization expert tasting appraisal, to meet the Ministry of Fresh Glutinous Corn Grade II standard. Determined by Mianyang Agricultural Science Research Institute of Sichuan Province for two years, branched-chain starch accounted for 100% of the total starch content, reaching the Ministry of glutinous corn standard (NY/T524-2002). Determined by Yangzhou University, branched-chain starch accounts for 98.52% of the total starch, and the rate of skin residue is 8.31%.
Yield performance: in 2005, 19 pilots, the average yield of 867.8kg per mu, 34.1% higher than the control, yield ranked No. 1; in 2004, the average yield of 891.1kg per mu, 30.3% higher than the control, yield ranked No. 1. In two years 39 points times, 39 points increased yield, average yield of 879.5kg per mu, 32.1% higher than the control average yield.
Validation opinion: the variety meets the national standard for corn variety validation, through the validation. Grain, economy, feeding, fruit and dual-purpose glutinous corn variety "Jingke glutinous 2000"
3.5 kg - 4 kg of seed per mu.
Second, do a good job of pre-sowing preparation
1. isolation conditions The sweetness of fruit corn is controlled by negative genes, if the string pollen with ordinary corn or different types of sweet corn, will produce pollen direct sensory phenomenon, into the ordinary corn, the loss of sweetness, affecting the quality of the fruit corn should be planted in isolation with other varieties of corn. Isolation methods are spatial isolation, time isolation and obstacle isolation, general spatial isolation distance of 300 meters, if time isolation, general sowing staggered period of 20 days or more, can also use villages, woods, hills and other obstacles to isolate, it is best to use spatial isolation.
2. Selection of land preparation To choose a flat terrain, uniform soil fertility, good irrigation conditions in the upper and middle fertility of the land, sowing before watering the bottom moisture water, a week after the fine rotary tillage, leveling the ground to achieve the ground flat and fine, stubble is not exposed, no clods of protruding, in order to facilitate the smooth emergence of the seed.
3. Sufficient bottom fertilizer in the plowing, per mu evenly spread organic fertilizer 50 kg, urea 40 kg, but pay attention to the seed fertilizer segregation.
4. Pave the film The conditions of the place can be implemented to pave the film planting. In some dry spring, less rain and windy, rainfall concentrated in July-September places, the film planting economic benefits are better. Because the film can not only improve the ground temperature, early sowing, so that the product early market, but also can prevent water evaporation, maintain soil moisture, reduce product production costs. Paving film can be paved artificially, or with a paving machine, generally with a distance of 100 cm, 80 cm wide, 15 cm high, the film should be straightened and tightened, paved, surrounded by soil cover tightly, every 2 meters with the soil pressure a windbreak, to prevent the wind from blowing up.
5. Selection of seed soaking 1-2 days of drying in the sunny days before sowing can improve the germination rate and germination potential of the seed, and then selected, remove the miscellaneous grains, broken grains, to prevent other seeds mixed in. If mixed with other ordinary corn, and ordinary corn growth, pollen, string pollen, the quality of fruit corn will be greatly reduced, and even can not be sold as fruit corn.
Clear water soaking seeds Cold water soaking seeds for 12 to 24 hours, or with 50 ℃ warm water soaking seeds for 6 to 12 hours, can make the seed germination, seedling fast and neat.
People's urine soaking seeds with 30% of people's urine 12 hours, or 50% of people's urine soaking seeds 6 to 8 hours, can accelerate the transformation of nutrients within the seed, conducive to the development of strong seedling, can increase yields of 5% to 10%.
Potassium dihydrogen phosphate dipping seeds with 500 times potassium dihydrogen phosphate solution dipping seeds for 8 to 12 hours, can be 1 to 2 days earlier than not dipping the corn seedlings, yield effect is obvious.
Sinophos seed mixing Use 50% Sinophos emulsion 50 grams, 20-40 kg of water, mix 250-500 kg of corn seed, can prevent and control underground pests in the seedling period.
Powder Rust Mixed with 25% Powder Rust WP at 0.4% of seed weight, can prevent and control jade
Powder Rust Mixed with 25% Powder Rust WP at 0.4% of seed weight, can prevent and control the seed of corn.
