First, choose a good seed off. Planting ryegrass should use fine varieties such as “Gooseberry†and “Selected No. 1â€, which are soft and have good attractability, good palatability, wide adaptability, and strong ability to reproduce. And we must use high-quality seed selected by machinery to sow seedlings to facilitate seedlings.
Second, timely sowing off. Ryegrass has strong regenerative ability, timely sowing is not only beneficial to Qimiao and strong seedlings, but also can increase the number of cuts in order to facilitate high yield. Autumn sowing is usually planted in the middle or late September, and sowing is to be finished at the latest by the end of October. It is not advisable to sow early, because sowing too early, the temperature is too high, unfavorable seedlings.
Third, the quality of planting. Before sowing, it is necessary to finely prepare the soil and apply sufficient basic fertilizer. In general, 500-750 kg of fermented and excreted human urine is used per acre, and 15-20 kg of three-element compound fertilizer of nitrogen, phosphorus and potassium are used as base fertilizer. When sowing, the soil can not accumulate water, and it should not be too dry, otherwise it will affect the germination. If the soil is too dry, horse water moist soil should be irrigated before sowing, and serious water accumulation should be drained. Single-season paddy fields or free fields are generally dominated by drills, with a spacing of 20-30 cm and a sowing depth of about 2 cm. Double-cropping paddy fields should be planted 7-10 days before harvest. Before sowing, the seeds were mixed with river mud and then sowed. After sowing, the rice plants were sown with bamboo shoots to allow all of the ryegrass seeds that fell on the rice plants to enter the ground. The amount of 1-1.5 kilograms per acre is better, and the seed quality can be increased by the appropriate amount to promote seedlings.
Fourth, seedling management. After the seedlings are grown, 400 to 500 kilograms of urea and 4-5 kg ​​of urea are applied topped with Maturation to promote rapid seedling growth. In addition, 3-5 kg ​​of urea shall be used to apply fertilizer once after each cut. General seedling height 30-40 cm can be cut green, life can be cut 4-5 times, but the seedlings can not cut more than 2 times, otherwise it will seriously affect the seedling production.
