Wheat Bottle Grass Cultivation Technology

1, the right time to sow

Wheat Bottle Grass is generally in the cold dew (October 8 or so) to frost (October 23 or so) sowing, snow (November 22 or so) can still be sown before; spring cultivation, the temperature reaches 6 ℃ or more can be sowed, the sowing period can be extended to the end of April. The end of the month.

2, land preparation and fertilization

Wheat bottle grass is not strict on soil requirements, but it is appropriate to choose convenient drainage and irrigation, deep fertile soil planting. Before sowing the need for fine ground preparation, deep turning 30-40 cm, per mu of fully rotted high quality organic fertilizer 1500-2000 kg as fertilizer, fine harrowing 2-3 times, leveling, do 120 cm wide, 15 cm high small raised beds.

3, sowing

Before sowing, mix the seeds with fine soil at a ratio of 1:10. Sowing, about 1 kg of seed per mu. After sowing, use a nail harrow to shallowly rake once, so that the seeds and soil are in full contact with each other, while covering the soil thickness of 0.2-0.5 centimeters, immediately sprayed with water. Sowing before and after Qingming, the temperature is suitable, usually 3-4 days to seedlings, 7 days Qi Miao; early October sowing.

4, field management

Wheat bottle grass root distribution is shallow, the entire growing period should keep the soil moist, especially in the spring cultivation, the growth period is shorter, the growth rate is faster, be sure to keep the soil moist, timely fertilizer, reasonable allocation of nitrogen, potassium fertilizer. Spring raw can be through the water fertilizer integration facilities per mu of urea 2 kg, aluminum dihydrogen phosphate 1 kg, every 15 days to apply a fertilizer.
