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.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a high-efficiency cultivation method for interplanting watercress and late rice with lotus root. 【Background technique】 [0002] Lotus root, referred to as lotus, alias lotus vegetable, lotus root, etc., originated in my country and has a history of more than 3,000 years of cultivation in my country. It is a very versatile aquatic economic crop. It is not only edible and medicinal, but also One of China's top ten famous flowers, deeply loved by the broad masses of the people. [0003] Watercress (scientific name: Nasturtium officinale R.Br.), also known as watercress, watercress, cold dish, resistant lettuce, water mustard, water pod, etc., is a cruciferous vegetable and a perennial aquatic herb. It is native to Europe and is planted in many parts of my country, India and Southeast Asia. It is cultivated in Guangdong, Guangxi, Fujian, Taiwan, Shanghai...

AI Technical Summary

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 difficult to popularize and apply

When interplanting late rice seedlings, it is necessary to remove dead branches and old leaves of lotus root in advance or crack some older leaves with small bamboo slices to reduce the number of concealment and trampling in the field; The number of transplanted seedlings is about twice that of double-cropping late rice to achieve high yields by relying on basic seedlings to form ears. When harvesting rice, the interplanting field must also maintain moisture, resulting in muddy interplanting fields that cannot be harvested by machinery, and manual harvesting is very labor-intensive.
