Abstract

The invention discloses a saffron and ecological summer cabbage interplanting cultivation method, and relates to the technical field of crop interplanting cultivation. According to the method, ecological summer cabbages are planted in summer dormancy (6-8 months), a single-season cultivation mode is upgraded to a annual interplanting mode, the land resource utilization rate and the economic benefit of unit area are remarkably improved, through interplanting design, the canopy of the ecological summer cabbages can effectively shield strong light insolation in summer, the water evaporation and nutrient loss of soil are reduced, meanwhile, the root system activity and the residue returning to the field can improve the organic matter content of the soil, the soil aggregate structure is improved, the soil hardening is avoided, a high-quality soil environment is provided for the subsequent growth of the saffron, the water fertilizer and the pH environment required by the growth of the saffron can be stably maintained through combining a customized cultivation soil formula with the soil conservation effect of the interplanting mode, the occurrence of plant diseases and insect pests is reduced, and the quality of saffron seed balls and the content of active ingredients are improved.

Description

Interplanting cultivation method for saffron and ecological summer cabbage Technical Field The invention relates to the technical field of crop interplanting cultivation, in particular to a method for interplanting saffron and ecological summer cabbage. Background Saffron is a rare medicinal and economic crop, the growth cycle is concentrated in 9 months of each year to 5 middle of the next year, saffron seedlings enter a mature dormancy stage after 5 middle of the year, field plots enter an idle stage, and the problems of low land resource utilization rate, serious loss of soil water and nutrients, soil hardening, soil fertility reduction and the like caused by high-temperature insolation in summer exist, so that the sustainable development of the saffron industry is restricted. In the prior art, the saffron is planted in a single-season cultivation mode, an effective soil conservation and efficient utilization scheme is lacked in the idle period in summer, and partial attempted summer idle crops have the defects of low matching degree with saffron growth requirements, poor soil improvement effect, limited economic benefit improvement and the like, and a set of standardized interplanting cultivation system which takes into account the efficient utilization of land, soil water and fertilizer conservation, saffron quality assurance and additional economic benefit is not formed. There is therefore a need to propose a new solution to the above problems. Disclosure of Invention The invention aims to provide a method for interplanting saffron and ecological summer cabbage, which aims to solve the problems of low land utilization rate, serious soil water and fertilizer loss in summer, soil productivity decline, insufficient economic benefit and the like in the conventional single-season cultivation of saffron. In order to achieve the aim, the invention provides the following technical scheme that the interplanting cultivation method of the saffron and the ecological summer cabbage at least comprises the following steps: S1, planting saffron crocus seed balls in 9 months each year, performing conventional cultivation management, mature saffron crocus seedlings enter a dormant state from the growing period to the middle 5 months of the next year, harvesting saffron crocus products and retaining part of cultivation soil; S2, preparing cultivation soil as an interplanting cultivation medium, wherein the interplanting cultivation medium comprises cultivation soil, fermented cow dung, ecological fertilizer, humus soil and fungus material; s3, planting ecological summer cabbages in the cultivation soil after the saffron is dormant in the last ten days of 6 months, completing a growth period by using the idle period of 6-8 months, and harvesting ecology Xia Baicai in the last ten days of 8 months to the last ten days of 9 months by shielding sunlight by the ecological summer cabbages plants and protecting soil water and fertilizer; S4, after the ecological summer cabbage is harvested, crushing plant residues, returning to the field, supplementing the plant residues into cultivation soil, and planting saffron crocus seed balls again for 9 months to realize annual circulation interplanting. Further, the mass percentage of the fermented cow dung in the interplanting cultivation medium is 25%, the mass percentage of the ecological fertilizer in the interplanting cultivation medium is 15%, the mass percentage of the humus soil in the interplanting cultivation medium is 10%, the mass percentage of the fungus material is 0.2%, and the rest mass percentage in the interplanting cultivation medium is the proportion of the interplanting cultivation medium.
