Second, high quality and high yield cultivation points:
1. Timely planting of this variety is suitable for the sowing date from the end of October to the beginning of November, not earlier than October 20, to prevent years of excessive growth or jointing phenomenon, to prevent freezing in winter and early spring. When sowing is done, it is necessary to finely prepare the soil. The wheat can not receive a few gutters from Guan Jian. Therefore, it is necessary to connect the gutters to facilitate drought relief.
2. The reasonable close planting generally requires about 150,000 basic seedlings per acre. Under different sowing dates, different cornices and different fertility levels, the range of suitable basic seedlings is 14-18 million, which means that the field with poor fertility is late. Broadcasting blocks can increase the density appropriately.
3. The scientific fertilization target production yields about 500 kilograms of field, generally Mushi N8-8 kg, phosphorus pentoxide 6-8 kg, namely ammonium bicarbonate 35-40 kg, phosphate fertilizer 25-30 kg. Reapply basic fertilizer and apply fertilizer early.
4. Comprehensive prevention and control of pests and weeds can be used for seed dressing before sowing, closed weeding with chemical herbicides after sowing, and timely prevention and control of pests and diseases based on pest information. Strengthen the field management, timely ditch pits against waterlogging.
High-yield Cultivation Techniques of China Damai No.2
I. Characteristics Huama 2 is a new high-yield and high-quality barley variety developed by Huanongda. It participated in the regional trial of the province from 1996 to 1998, with a yield of 373 kg per mu in each year, equivalent to the output of the second beer, 96- In 1997, the highest local planting area was 634.7 kg per mu, which was 13.4% higher than that of Ejipi No. 2 and the increase in output was extremely significant. The variety has high yield and stability. This species is a semi-wintered, double-leaved winter wheat seedling. The seedlings grow for a long while, the leaves are dark green, the ears are red, the tillering power is middle and the spike rate is high, the effective ear is 433 thousand-45 thousand, the number of ears per spike is more than 23, and the grain weight is 42.6. g. The structure of production is coordinated and the ear layer is neat. Plant height of about 88 cm, good lodging resistance, strong disease resistance, high resistance to powdery mildew, head blight, stripe disease, smut, rust, no net spot, paddy field cultivated light sheath blight, cold resistance Resistant to drought and stains.
