Lotus rhizome interplanting Nasturtium officinale R.Br. and late rice high efficiency cultivation method

Abstract

The invention provides a lotus rhizome interplanting Nasturtium officinale R.Br. and late rice high efficiency cultivation method mainly comprising the following steps: 1, selecting Yexiangyou rice seed, Lianxiang no.1 lotus rhizome seed and first generation Nasturtium officinale R.Br. seed; 2, selecting fertile soil field with strong water retention fertilizer conservation capability as the interplanting field; 3, planting at proper time; 4, reasonably closely planting; 5, reasonably applying fertilizers; 6, timely controlling insect and diseases. The method can realize interplanting of the lotus rhizome, Nasturtium officinale R.Br. and late rice, and can greatly reduce base fertilizer and topdressing application amount; the Nasturtium officinale R.Br. interplanting method can protect the lotus rhizome for safe overwintering, can improve soil temperature, thus advancing lotus rhizome seed germination growth time, and the lotus rhizome harvesting time can be advanced by 15-20 days when compared with other methods; the Nasturtium officinale R.Br. can be pressed into the mud in April of the next year so as to serve the lotus rhizome green fertilizer, thus reducing lotus rhizome additional fertilizer frequency and fertilizer amount; the late rice paddy rice tillering is normal, and the interplanting paddy rice needs no pesticide sprinkling, no fertilizer is needed, and the throw inserting seedling number is no difference from the double cropping late rice.

Problems solved by technology

[0005] However, the existing lotus root interplanting with other crops or economic crop cultivation techniques has the following technical defects: the amount of basal fertilizer applied before planting lotus root and the top dressing after planting are all very large; lotus root can only be planted after the temperature is higher than 15°C in the beginning of spring , the harvest season is at the same time as the non-interplanted lotus root, and it cannot be sold first. At this time, the price is relatively cheap. The rate still needs to be improved, coupled with cumbersome work and high labor intensity, it is dif
