Introduction to the Longchuang 310 Corn Variety and Its Characteristics

For corn growers, the worst thing is uncooperative weather; prolonged high-temperature heat damage can cause massive corn yield reductions, so better corn varieties are needed to solve this problem. So where do the advantages of the Longchuang 310 corn seed lie? The following is an introduction to the Longchuang 310 corn seed.

I. Introduction to the Longchuang 310 Corn Seed

The Longchuang 310 corn seed has thick, sturdy roots and stems, strong lodging resistance, and good drought and heat tolerance. It is unaffected by extreme weather and has stable yields. From emergence to maturity is about 103 days. The plant type is compact, and the ear is cylindrical. It is resistant to stalk rot, ear rot, and southern rust, and susceptible to southern leaf blight and head smut. The grain test weight is 764 g/L, the crude protein content is 10.86%, the crude fat content is 3.61%, the crude starch content is 72.45%, and the lysine content is 0.34%.

II. Corn Cultivation Techniques

1. Thinning and Final Stand Establishment

At the three-leaf stage, thin out the clustered corn seedlings; at the five-leaf stage, establish the final stand according to plant spacing. Remove diseased, weak, and off-type seedlings, and keep vigorous ones. Where there are gaps or missing plants in the rows, keep double plants at adjacent positions to fill them in.

2. Soil, Fertilizer, and Water Management

After the final stand is established, cultivate in time, clear the ridges and remove stubble to promote deeper root growth. Among these, the key measures to prevent lodging are increasing potassium fertilizer application, controlling water during the seedling stage, and preventing excessive density. Only with deep roots can corn have strong plants and strong lodging resistance. After 2-3 years of rotary tillage, the soil should be deep plowed once. Subsoil the soil to 35 cm, apply nitrogen fertilizer in split applications, and increase the application of organic fertilizer.

3. Pest, Disease, and Weed Control

During the seedling stage, control of aphids should be strengthened; 90% trichlorfon wettable powder at 2000 times dilution can be used for? spray control. At the large trumpet stage, mix 50% phoxim emulsion at 300 mL/hm2 with 70% carbendazim wettable powder at 1125 g/hm2 and dilute with 450 kg/hm2 of water for one-time control of pests and diseases, which can reduce the degree of pest and disease damage in the later stages of corn growth. For the double-spotted leaf beetle appearing at the tasseling and silking stages of corn, use 4.5% beta-cypermethrin at 1000 times dilution for control. For the Asian corn borer appearing at the tassel emergence stage, use trichlorfon at 1000 times dilution for whorl application, or apply phoxim granules at 22.5-30.0 kg/hm2 into the leaf whorl for control.

For chemical weed control, 40% acetochlor-atrazine suspension can be used at 2250 mL/hm2, diluted with 450 kg/hm2 of water, and evenly sprayed in the early morning or evening when there is no wind for pre-emergence weed control.

4. Timely Harvest

The suitable harvest period for corn is from the end of September to the beginning of October. When the husks are dry, the milk line of the kernels has disappeared, the black layer has appeared, and the moisture content is below 32%, choose mechanical harvesting, return the crushed straw to the field, and improve soil fertility. A large amount of practice has proven that late harvesting of corn can increase yield by 750-1500 kg/hm2, and the 1000-grain weight increases by more than 15%. When the kernel moisture content is less than 14%, choose a dry, well-ventilated site for storage.
