Problems solved by technology

Due to the need for seedling raising and transplanting, transplanting rapeseed requires high labor intensity, more labor and more flowering time; live-streaming rapeseed is carried out after the crops are harvested, the season is tense, the waste of warm and light resources before winter is serious, and the climatic conditions during the sowing period seriously restrict Sowing quality, leading to extensive management, unbalanced growth and unstable yield

Abstract

The invention discloses a process of rape undersowing in rice field, comprising following steps: (1) sowing rape seed 5- 7 days before rice harvest; (2) harvesting rice 5- 7 days after rape sowing; (3) fertilizing and weed removing 10- 14 days after rape sowing; (4) cleaning ditch 16- 20 days after sowing; (5) fertilizing and preventing aphid 95-98 days after sowing; (6) preventing sclerotia sclerotium with pesticide 150- 155 days after sowing; (7) harvesting rape 215- 220 after sowing. The invention makes use of suitable water, fertilizer and heat to sow rape under rice field to realize rape and rice intergrowth, which effectively releases pressure of larbor force, and season during autumn sowing.

Description

Technical field [0001] The invention relates to a rapeseed cultivation technique, in particular to a cultivation technique for inter-sowing rapeseed in paddy fields. Background technique [0002] Rapeseed is an important rapeseed crop in my country and the main source of edible oil in the southern region. In the long-term production practice, the working people have formed the rapeseed transplanting and direct-seeding cultivation techniques, which play their due role in the production in different regions and different production methods. Due to the need for seedling raising and transplanting, transplanting rapeseed requires high labor intensity, more labor and more flowering time; live-streaming rapeseed is carried out after the crops are harvested, the season is tense, the waste of warm and light resources before winter is serious, and the climatic conditions during the sowing period seriously restrict Sowing quality leads to extensive management, unbalanced growth and un...
