The main points of planting ryegrass cultivation technology are as follows:
First, the sowing period
More ryegrass can be sowed in spring and autumn. Autumn harvesting is used more frequently and the total output is higher. Spring sowing can extend the harvest and utilization period, and the grass is fresh, but the total production is relatively low. In Yongkang City, the seeding period for autumn sowing is from early September to mid-November, and is sown in early February in spring.
Second, sowing operation
Before planting, the Muzhan bar fertilizer is 1000-1500 kg. If there is no organic fertilizer such as pig bar, 25-30 kilograms of calcium, magnesium, phosphate fertilizer can be applied as base fertilizer. After fertilization, plough the land to do the trick. The ryegrass seed is small, and it is required that the buckwheat noodles be flat and no large clods. Seeding methods can be broadcast or sowing, but for management purposes, it is better to broadcast. The amount of mu for use is about 1.5 kg. If there is little rain or dry soil during the sowing period, soaking with fresh water can be used for 2-4 hours to facilitate seedling emergence and increase the rate of seedling establishment.
Third, management
Seedlings of ryegrass should be cultivated and weeded in time. After the peak period of drug dispensing, if the shade has been sealed, weeding may not be done. After each harvest, a small amount of nitrogen fertilizer should be applied to accelerate regeneration and increase production. Seedlings need to pay attention to tigers and earthworms. If found to use "toxic silk" pesticide control.
Fourth, the harvest of ryegrass
The ryegrass harvested grass layer height is about 30 cm. The sowing time, the number of times and the output are related to the fertilizer and water management conditions. In the early autumn, the seeds can be cut 1-2 times during the year, and the next spring can be cut about 4 times. Planted in October, if well managed, cut once a year. Cut 2-3 times after the year. Spring sowing, can be cut 3 times in June. Farmers can arrange the sowing time reasonably according to the feeding condition of livestock and poultry.
