First pass for building slant beds for early season cantaloupe production. Further shaping of the bed is required before planting. January 1996 |
| 1571797 |
field preparation |
|
Slant beds for early season cantaloupe production ready for planting. Note how the south-facing bed receives more direct exposure to sunlight. This side of the bed is where seed is planted. The south-facing slant raises soil temperature for quicker germination at a time of year when temperatures can be too low for cantaloupe planting. After the crop is established and before vines run, the top of the bed will be flattened or "knocked down". See 1571762-3 for first pass on bed formation. January 1996 |

melon |
Cucumis melo |
Early production of cantaloupe in the desert southwestern U.S. uses a mid-bed trench system. The field is seeded in a trench in the top of the bed and covered in plastic to form a miniature greenhouse. This protects plants from frost and heats soil to promote quick germination. As plants enlarge, plastic will be removed. January 1996 |

Final pass for building slant beds for early season cantaloupe production. Note how the south-facing bed receives more direct exposure to sunlight. This side of the bed is where seed is planted. The south-facing slant raises soil temperature for quicker germination at a time of year when temperatures can be too low for cantaloupe planting. After the crop is established and before vines run, the top of the bed will be flattened or "knocked down". See 1571762-3 for first pass. January 1996 |
