Problems solved by technology

However, these technologies at home and abroad all use nitrogen-fixing plants, herbaceous plants, etc., and their focus is on ecological and social benefits, without or seldom considering the economic benefits of plant hedges, and the alternative forms of plant hedges are especially economic plant hedges. Not many forms, not perfect technology

Embodiment 1

[0032] Embodiment 1: forage hedgerow soil conservation planting technology, it comprises following process:

[0033] Plowing and soil preparation: Before transplanting or sowing the hedgerows, the soil of the hedgerows should be plowed. The plowing depth is 10cm, the width of the site preparation is 50cm, and the soil is fined. Calcium phosphate 40 kg;

[0034] Sowing and raising seedlings: alfalfa is sown by direct seeding, the amount of seeds per mu is 1.5 kg, when sowing, the seeds are mixed with the sediment at a ratio of 1:2.5, and evenly spread on the hedgerows, after sowing, water 3m per mu 3 , covering soil 0.5cm, the best sowing time is from September to October, no need to thin out seedlings after emergence, but pay attention to remove weeds before the plants completely cover the soil, mow once a year in mid-April and mid-October, and leave stubble when mowing 5cm;

[0035] Planting: Hedgerows with a slope of 9° have a spacing of 800cm, and two rows of alfalfa are ...

Embodiment 2

[0036] Embodiment 2: forage hedgerow soil conservation planting technology, it comprises following process:

[0037] Plowing and soil preparation: Before transplanting or sowing the hedgerows, the soil of the hedgerows needs to be plowed. The plowing depth is 15cm, and the width of the site preparation is 60cm. Calcium phosphate 50 kg;

[0038] Sowing and raising seedlings: alfalfa is sown by direct seeding, the amount of seeds per mu is 2.5 kg, when sowing, the seeds are mixed with the silt at a ratio of 1:2.5, and evenly spread on the hedgerows, after sowing, water 4m per mu 3 , covering soil 1cm, the best sowing time is from September to October, no need to thin the seedlings after emergence, but pay attention to remove weeds before the plants completely cover the soil, mow once a year in mid-April and mid-October, leave 6cm of stubble when mowing ;

[0039] Planting: 700cm between hedgerows at a slope of 10°, three rows of alfalfa are densely planted in bands at interval...

Embodiment 3

[0040] Embodiment 3: forage grass hedgerow soil conservation planting technology, it comprises following process:

[0041] Plowing and soil preparation: Before transplanting or sowing the hedgerows, the soil of the hedgerows needs to be plowed. The plowing depth is 14cm, the width of the site preparation is 57cm, and the soil is fined. Calcium phosphate 47 kg;

[0042] Sowing and raising seedlings: Vetiver is planted by transplanting seedlings. Two rows are planted for each hedgerow, with a row spacing of 45cm and a plant spacing of 20cm. One seedling is planted in each litter. From October to November, in the second year from February to March, the seedlings are replenished once according to the survival situation, and they are mowed once a year in October, leaving 40cm of stubble during mowing.

[0043] Planting: Slope 12° Hedgerow spacing 700cm, vetiver is densely planted in a belt every 900cm along the contour line, vetiver quickly forms hedgerows on the slope, terraced s...

Abstract

The invention discloses a forage hedgerow soil conservation planting technology, comprising the following steps of: tillage and land preparation, seeding and seedling, and plantation. The technology has the following advantages that: the forage hedgerow can prominently reduce sediment loss amount and runoff and has good effect of fast controlling water and soil loss; the forage hedgerow promotes value-cost ratio of energy of the entire system and becomes an effective measure to enhance the agricultural efficiency in hilly areas; bean forage hedgerow can offer excellent shelter to ground spider so as to enrich the diversity of spiders in farmland. The technology not only focuses on ecological and social benefits, but can also create economical benefit, in addition, the technology realizes sustainable agricultural development on dry hillside fields, effectually controls water and soil loss of dry hillside farmlands, enriches soil fertility, enhances grain yield and can also produce a certain amount of high-grade forage to further guarantee the supply of partial feed for the development of animal husbandry in agricultural regions.

Description

technical field [0001] The invention relates to a soil-conserving planting technique, in particular to a forage hedgerow and soil-conserving planting technique. Background technique [0002] Hedgerows were proposed by researchers from the Nigerian International Institute of Tropical Agriculture (IITA) in the late 1970s. Hedgerows are a special form of agroforestry and are defined as “a production system of crops interspersed with woody plants, shrubs (fast-growing legumes are best) and perennial hedgerows on agricultural land” (Kang, 1993 ). Hedgerows are usually planted in rows, which can be widely or narrowly spaced. On sloping land, hedgerows are planted across slopes to prevent soil erosion, so the term horizontal hedgerow farming is used. The Philippines has developed this technology into a series of technologies for preventing soil erosion, which are collectively referred to as comprehensive technologies for farming slopes. In recent years, China has also been comm...
