Introduction of Longchuang 310 Maize species

For corn growers, the most fear is that the weather is not beautiful, a long period of high temperature heat damage will lead to a substantial reduction in corn production, so better corn varieties are needed to solve this problem. What is the advantage of Longchuang 310 corn seed? The following is an introduction of Longchuang 310 corn species.

1. Introduction of Longchuang 310 corn species

Longchuang 310 maize seed has strong rhizome, strong lodging resistance, good drought and heat resistance, not affected by extreme weather, and stable yield. It takes about 103 days from emergence to maturity, compact plant type, ear tube type, resistance to stem rot, ear rot, southern rust, susceptible leaf spot and powdery mildew. The grain bulk density 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. Planting techniques of Maize

1. Fixed seedling

Maize seedlings in the three-leaf stage open, 5 leaves can be determined according to plant distance, to pull out diseased seedlings, weak seedlings, different plants, stay strong seedlings; in case of lack of seedlings and broken ridges, two plants should be left adjacent to replenish seedlings.

2. Soil, fertilizer and water management

After setting the seedlings, ploughing in time, clearing ridges and eliminating stubble, promoting root rooting. Among them, the key measures to prevent lodging are increasing the application of potash fertilizer, controlling water at seedling stage and preventing overdensity. Only with deep roots can corn have strong plant strength and strong lodging resistance, and the soil should be turned deep once after 2-3 years of rotary tillage. Subsoiling soil 35cm, applying nitrogen fertilizer in stages and increasing organic fertilizer.

3. Control of diseases, insect pests and weeds

The prevention and control of aphids should be strengthened at the seedling stage, and 2000 times of 90% trichlorfon wettable powder can be selected. Spray control: 50% phoxim emulsion 300mL/hm2 and 70% carbendazim wettable powder 1125g/hm2 were mixed with water 450kg/hm2 in the big trumpet stage to control diseases and insect pests at one time, which can reduce the damage degree of diseases and insect pests in the later stage of corn growth. 4.5% cypermethrin 1000 times solution was selected to control the double-spotted firefly beetles in the male and silking stage of corn. 1000 times solution of trichlorfon was used to infuse the corn borer in the male stage, or phoxim granules were sprinkled into the heart leaves to control the disease.

Chemical weeding can use 40% atrazine water 2250mL/hm2, mixed with water 450kg/hm2, in the morning and evening when there is no wind to spray closed weeding.

4. Timely harvest

The suitable harvest period of corn is from the end of September to the beginning of October. When the bracts dried up, the grain milk line disappeared, the black layer appeared and the water content was less than 32%, the mechanical harvest was selected, the straw was crushed and returned to the field, and the soil fertility was improved. A large number of practices have proved that the late harvest of corn can increase the yield by 750-1500kg/hm2 and the 1000-grain weight by more than 15%. When the grain water content is less than 14%, choose a dry and ventilated site for storage.
