A kind of interplanting cultivation method of Yuanhu and taro

Abstract

The invention discloses a Rhizome corydalis and taro interplanting cultivation method comprising the following steps: simultaneously sowing Rhizome corydalis and taro from the first 10 days of October to the first 10days of November, wherein the taro is sowed, and then Rhizome corydalis is sowed; harvesting the rhizoma corydalis 4-6 days after the rhizoma corydalis plant is fully withered in the first 10 days of May, returning the rhizoma corydalis withered plants back to the soil, and earthing up the taro; drying the land after autumn begins; cutting petioles on the ground before harvesting, and harvesting the taro after wounds heal, wherein the best harvesting time is when the taro leaves turn yellow and fibres whither. The method simultaneously sow the Rhizome corydalis and taro, so taro sowing safe overwintering problems can be solved; two crops can be planted in one season, thus improving land utilization rate, and increasing yield per unit area; heavy fertilizer is applied in the Rhizome corydalis growth period, yet the fertilizer utilization rate is low, so mass fertilizer can be left after harvesting; the left fertilizer can be utilized by the interplanting taro, thus greatly improving fertilizer utilization rate.

Description

technical field [0001] The invention belongs to the technical field of planting of Yuanhu and taro, in particular to an intercropping cultivation method of Yuanhu and taro. Background technique [0002] In the mountainous areas of Zhejiang, the most suitable sowing period of Yuanhu is from mid-late October to early November. The taro is broadcast live in the open field, and it is suitable for sowing in late March to early April. Taro will be damaged when it is below 0°C or above 25°C; below 0°C, it will be frozen, which will cause rot due to frostbite; below 7°C, the epidermis will also be easily infected by microorganisms and rot, and higher than 25°C will also cause Rot and dehydration; no reports of taro overwintering. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: aiming at the deficiencies in the prior art, an interplanting cultivation method of Yuanhu and taro with high utilization rate of land and fertilizer is pr...

Problems solved by technology

Taro will be damaged when it is below 0°C or above 25°C; if it is below 0°C, it will be frozen, and it will rot due to frostbite. If it is below 7°C, the skin will be easily infected by microorganisms and rot, and if it is above 25°C, it will also cause rot. Rotting and dehydration; taro sowing and overwintering have never been reported
