Large-scale high-yield hybrid seed production method for pumpkins

Abstract

The invention discloses a large-scale high-yield hybrid seed production method for pumpkins. The method comprises the following steps of 1, space isolation; 2, land selection and preparation; 3, parent seed treatment; 4, mechanical seeding; 5, male parent male induction treatment; 6, female parent female promoting and pruning treatment; 7, field management; 8, honeybee pollination; 9, pest control; 10, mechanical harvesting; and 11, seed treatment; The large-scale high-yield hybrid seed production method for pumpkins standardizes pumpkin hybrid seed production, simplifies the production technology, reduces labor, improves the yield and quality of pumpkin hybrid seeds, improves the scale benefit, is suitable for large-scale production and popularization of hybrid melon vegetable seeds, is small in seed setting rate difference and stable in yield, and does not need ridging, reduces watering, pollination and the like; and labor force is reduced, labor cost is low, expenditure is small, drip irrigation saves water resources, the use amount of chemical fertilizer is reduced, and agricultural chemical fertilizer pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a large-scale high-yield hybrid seed production method for pumpkins. Background technique [0002] Pumpkin for seeds is a general term for pumpkins whose seeds are the main edible organ or processing object, including zucchini for seeds, pumpkin with rough edges, white plate pumpkin, Mexican pumpkin, Yunnan black-seeded pumpkin, etc., covering all cultivated species of pumpkin. Currently, seeds The cultivation of pumpkins is mainly self-owned varieties, and there are basically no imported hybrid varieties. Among them, zucchini for seeds accounts for more than 70% of the planting area of ​​pumpkins for seeds, and all hybrid varieties have been used, such as Hope 9, Jinfeng 8, and Derui 9. etc.; shellless types such as Golden Apple Three Stars, Four Stars, King of Kings, Ruibao 601, etc. White plate pumpkin seeds account for about 20% of the total sown area of ​​pumpkins for ...

[0002] Pumpkin for seeds is a general term for pumpkins whose seeds are the main edible organ or processing object, including zucchini for seeds, pumpkin with rough edges, white plate pumpkin, Mexican pumpkin, Yunnan black-seeded pumpkin, etc., covering all cultivated species of pumpkin. Currently, seeds The cultivation of pumpkins is mainly self-owned varieties, and there are basically no imported hybrid varieties. Among them, zucchini for seeds accounts for more than 70% of the planting area of ​​pumpkins for seeds, and all hybrid varieties have been used, such as Hope 9, Jinfeng 8, and Derui 9. etc.; shellless types such as Golden Apple Three Stars, Four Stars, King of Kings, Ruibao 601, etc. White plate pumpkin seeds account for about 20% of the total sown area of ​​pumpkins for seeds, and are mainly conventional varieties; rough pumpkin seeds are still used by farmers at present. Varieties are the main varieties, accounting for about 8% of the total sown area of ​​pumpkins for seeds, and black-seeded pumpkins account for 1% of the total sown area of ​​pumpkins for seeds. ~333,000 hectares. However, in recent years, due to the accelerated concentration of rural land transfer, the transfer of rural labor force, the reduction of rural labor force and the continuous increase of labor costs, labor-intensive pumpkin seed production has orders but no one planted it;

[0003] On the one hand, the traditional pumpkin hybrid seed production method adopts artificial ridge mulching and artificial assisted pollination to achieve seed production. The seeds produced are affected by artificial pollination, the seed setting rate varies greatly, and the yield is unstable. Watering, pollination, etc. require a lot of labor, and the labor cost is high and the expenditure is large.

Secondly, the traditional large-scale flood irrigation not only wastes a lot of water resources, but also increases the use of chemical fertilizers, causing agricultural chemical fertilizer pollution; in view of these defects, it is necessary to design a large-scale and high-yield hybrid seed production method for pumpkins
