Problems solved by technology

[0003] In this planting method in the southern hilly area, the forage corn is generally planted in early June and mowed in late August, and the ryegrass is planted in October. After the corn is harvested in August and before the ryegrass is planted in October, there are nearly two The main reasons for the idle interval of one month are as follows: first, the short time cannot meet the growth of summer sowing corn; second, the middle and late August is in the summer high temperature and drought stage, which is not conducive to corn planting
Therefore, this interval causes the land to be idle and the total land output value is not high, which is contrary to the current shortage of forage land and low forage production in the southern region.

Embodiment 1

[0027] A forage rotation production method with high multiple cropping index, comprising the following specific steps:

[0028] (1) Planting of spring-sown forage corn: in mid-April, after harvesting open space, wasteland or previous crops, use five-share plows to deeply plough the land, apply 1 ton / mu of organic fertilizer, and use a rotary tiller to gently rotate The fertilizer is spun into the soil, and after the land is leveled, the corn planter is used to sow the spring-sown forage corn with a row spacing of 0.5 meters and a plant spacing of 0.20 meters. After sowing, the spring-sown forage corn is routinely managed;

[0029] (2) Planting of summer-sown forage corn: in early and mid-July, during the spring-sowed forage corn milk maturity period, the silage harvester was used to harvest the spring-sown forage corn, and after the land was re-spinned, Planting summer-sown forage corn, the sowing method is the same as step (2), to ensure that the sowing is completed before Ju...

Embodiment 2

[0033] A forage rotation production method with high multiple cropping index, comprising the following specific steps:

[0034] (1) Planting of spring-sown forage corn: in mid-April, after harvesting the open space, wasteland or previous crops, use five-share plows to deeply plough the land, apply 30 kg / mu of compound fertilizer, and use a rotary cultivator to gently rotate the land. The fertilizer is spun into the soil, and after the land is leveled, the corn planter is used to sow the spring-sown forage corn with a row spacing of 0.6 meters and a plant spacing of 0.30 meters. After sowing, the spring-sown forage corn is routinely managed;

[0035](2) Planting of summer-sown forage corn: in early and mid-July, during the spring-sowed forage corn milk maturity period, the silage harvester was used to harvest the spring-sown forage corn, and after the land was re-spinned, Planting summer-sown forage corn, the sowing method is the same as step (2), to ensure that the sowing is c...

Embodiment 3

[0039] A forage rotation production method with high multiple cropping index, comprising the following specific steps:

[0040] (1) Planting of spring-sown forage corn: in mid-April, after harvesting open space, wasteland or previous crops, use five-share plough to deeply plough the land, apply 3 tons / mu of organic fertilizer, and use a rotary cultivator to gently rotate the land. The fertilizer is spun into the soil, and after the land is leveled, the corn planter is used to sow the spring fodder corn with a row spacing of 0.6 meters and a plant spacing of 0.22 meters, and routine management of the spring fodder corn is carried out after sowing;

[0041] (2) Planting of summer-sown forage corn: in early and mid-July, during the spring-sowed forage corn milk maturity period, the silage harvester was used to harvest the spring-sown forage corn, and after the land was re-spinned, Planting summer-sown forage corn, the sowing method is the same as step (2), to ensure that the sowi...

Abstract

The invention belongs to the technical field of forage grass planting, and particularly relates to a forage grass crop rotation production method with a high multiple cropping index, the forage grass crop rotation production method is carried out according to a crop rotation mode of spring sowing feeding corn, summer sowing feeding corn and lolium multiflorum, and according to the growth characteristics of the spring sowing feeding corn, the summer sowing feeding corn and the lolium multiflorum, the multiple cropping index of the forage grass is increased. Sowing time nodes are controlled, spring sowing feeding corn is sown in the middle of April, and harvesting is conducted in the first ten days and the middle ten days of July; sowing summer sowing feeding corn before late July, and harvesting in early and middle October; lolium multiflorum is sown before mid-to-late October, harvesting is conducted before mid-April, and next crop rotation planting is continued after harvesting is completed. According to efficient mechanical operation and forage grass growth characteristics, time nodes are well grasped, three-season forage grass rotation planting of spring sowing feeding corn, summer sowing feeding corn and lolium multiflorum is achieved, the land multiple cropping index and the fresh grass yield per unit area are improved, and economic benefits are good.

Description

technical field [0001] The invention belongs to the technical field of forage grass planting, and in particular relates to a production method for forage grass rotation with high multiple cropping index. Background technique [0002] At present, according to the different farming systems, production levels and ecological conditions in different parts of China, corn production in the north and northwest regions is mainly based on spring corn or summer corn in one season, and rotation with wheat or oats in autumn and winter. The terrain in the southwestern region is complex, and intercropping between corn and wheat, sweet potato or beans is mainly practiced in the mountainous highlands; only one season of spring corn can be planted in the alpine mountainous areas. In the southern hilly corn area, forage corn is mainly planted in the "forage corn - multiflora ryegrass" forage rotation mode or with "radish, cabbage" and other vegetable cash crops, basically in a single planting ...
