I'm from Yaodu District, Shanxi Province. Is it okay to grow ryegrass? How many years does it take to harvest? How many varieties can you recommend?

If you want to harvest for many years, you can plant perennial ryegrass.

1, land selection and land preparation

Lolium perenne has strong adaptability, high yield, alkali resistance, barren resistance, cold resistance, pest resistance, many tillers, strong regeneration ability and high requirements for water and fertilizer, so it is suitable to be planted in loose and fertile plots with good drainage. Before sowing, turn over the soil to make it more subdivided and apply base fertilizer appropriately. Generally, 5000 kg of soil miscellaneous fertilizer, 40 kg of calcium superphosphate and 25 kg of ammonium bicarbonate should be applied per mu.

Step 2 sow seeds

(1) is usually carried out in spring or autumn. Before sowing, the seeds should be placed in the sun for about 1 hour, and then soaked in clear water for 12 hours, so that the seeds can fully absorb water and germinate in advance. The seeds can be directly mixed with calcium magnesium phosphate fertilizer for sowing.

(2) The most widely used sowing method is drilling. Generally, the sowing amount is 7.5- 10 kg per mu, which is appropriately increased or decreased according to soil moisture, soil preparation quality and seed germination rate. After sowing, cover it with soil and water it.

(3) If the weather is dry or the soil is dry, it is necessary to irrigate properly. Seeds germinate faster. Pay attention to weeding after germination. Herbicide can be sprayed, and there will be a large grassland in less than a month.

3. Post management

Weeds should be removed in time during the growth of ryegrass seedlings, and soil should be loosened and fertilized appropriately. Fertilization should be carried out after harvest to avoid burning stubble.

Step 4 harvest

Cut the grass about 50 days after sowing, regardless of the growth strength. After harvesting every 20-30 days, ryegrass should be watered and fertilized to supplement the nutrients needed for growth. Lolium perenne has good trampling resistance, natural grazing is also possible, and it can grow rapidly. In order to solve the problem of lack of green feed in winter, green storage can be carried out after harvest.
