Embodiment 2

[0029] 2.1 Planting of rapeseed: variety Huayouza 62, sown on September 28, 667m 2 Apply 50kg of slow-release fertilizer specially for rapeseed as base fertilizer; add 10 kg / 667m of urea on December 19 2 , chase urea 10 kg / 667m on February 10 2 ;

[0030] 1.2 Cycle Harvesting: For the first round of forage rapeseed, a part of the forage rapeseed is harvested sequentially, and the harvesting time is on December 19, February 10, and April 7 (harvest once for comparison), etc. For the first time, the three-leaf harvest is used Way. In the second round, the regenerated rapeseed harvested in the first round is successively harvested, and it is carried out in the full flowering stage of the regenerated rapeseed. Each harvest area is determined according to the actual demand for feed;

Embodiment 3

[0036] 3.1 Planting of rapeseed: variety Huayouza 62, sown on September 20, 667m 2 Apply base fertilizer 50% compound fertilizer 50 kg; on December 19, chase urea 10 kg / 667m 2 , chase urea 10 kg / 667m on February 10 2 .

[0037] 3.2 Cycle Harvesting: For the first round of forage rapeseed, part of the forage rapeseed is harvested sequentially, and the harvesting time is on November 10 (harvest three times), February 10 (harvest twice), April 13 (harvest once for comparison), etc. , for the first time adopting the harvesting method of paying attention to leaves.

[0038] The second round harvested the regenerated rapeseed harvested in the first round on February 10, using the three-leaf harvesting method. The third round was carried out on May 14th when the regenerated rapeseed was in full bloom. Each harvest area is determined according to the actual demand for feed.

Embodiment 4

[0044] Effect of different harvesting methods on the yield of forage rapeseed. The result is as follows:

[0045] Table 4 Effects of three harvesting methods on the fresh weight yield of forage rapeseed

[0046] .

[0047] It can be seen from the above that the yield of the three leaves and the heart leaves is higher, and the yield of the heart leaves is lower.

Abstract

The invention discloses a circulating harvesting culturing method of feed rape suitable for Hubei province and Yangtze river basin. The method comprises the steps that sowing is conducted at the beginning of September to the late October, the sowing amount is 300 g / 667 m<2>, and the density is 30,000 / 667 m<2> or above; harvesting for the first time can be conducted when the feed rape reaches the height around 10-15 cm; regenerated rape harvested in the first round is sequentially harvested in the second round; top dressing can be conducted within three days after the rape is harvested, or halftop dressing is conducted within three days after the rape is harvested, and half top dressing is conducted again around the winter solstice; urea per mu is normally around 20kg / 667 m<2>; a harvesting manner of leaving three leaves or leaving core leaves is adopted at the very first several harvesting under a multiple harvesting condition. According to the method, effective supplying of feed in the whole winter-spring season is achieved, the scarcity and waste of the feed when concentrated harvesting is conducted is prevented, and the full use of the production potential of the feed rape is made.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method of forage rapeseed. Background technique [0002] The planting area and output of rapeseed in Hubei Province rank first in the country for 19 consecutive years. However, the rapeseed industry, which mainly produces rapeseed, has a low degree of mechanization, and the relative efficiency of rapeseed production has declined. Especially in 2015, the state canceled the rapeseed purchase and subsidy policy for improved varieties, and at the same time liberalized the rapeseed import policy, resulting in the price list of rapeseed. The decline has seriously reduced the enthusiasm of farmers to plant rapeseed, and the production of rapeseed has shown a sharp decline. The multifunctional development of rapeseed is an inevitable trend to revive the rapeseed industry, and rapeseed feed production is one of the important ways. [0003] Feed rapeseed belongs to...
