Problems solved by technology

Although the utilization rate of the lotus root field has been partially improved like this, and the output of the lotus root has been increased, the defects of this cultivation method still exist: one, the scope of application is very limited, only limited to the south of the Tropic of Cancer, and there is no lotus root throughout the year. Second, the demand for lotus root is very large, and the two sowings add up to 600-700 kilograms of lotus root per mu (one mu is equal to 667 square meters). Third, the yield of fresh lotus root per mu is very low. The two harvests add up to 1750-2500 kg of lotus root per mu of lotus root field

Embodiment Construction

[0015] Below in conjunction with specific embodiment of the present invention is described in further detail:

[0016] The double crop cultivation method of lotus root proposed by the present invention may further comprise the steps:

[0017] 1) Variety selection: It is more suitable to use the mid-maturing variety Elian No. 5 as the seed lotus root. It has the advantages of short development time and fast growth rate, especially the rapid growth and development of the side whip of this variety, and has the inherent attribute of high yield per unit area. The characteristics and planting season of the mature variety are also very suitable for double cropping treatment.

[0018] 2) Selection of lotus root fields: It is more suitable to select lotus root fields with a silt depth of 35-40 cm and an organic matter content in the silt greater than 2.6%. In this way, on the one hand, the compatibility of the lotus root field is good, which is beneficial to various cultivation treatm...

Abstract

The invention discloses a double-cropping cultivation method of lotus roots. According to the principle of a double-cropping cultivation technique of lotus roots, in the process that a fresh lotus root enlarges on a main lotus root, after a first formation period is completed, the fresh lotus root on the main lotus root is excavated in time, the apical dominance is removed, side lotus roots are promoted to further grow by utilizing the nutrient components generated from lotus leaves above the water level of a lotus root field, and fresh lotus roots are generated after regrowth.

Description

technical field [0001] The present invention relates to the cultivation technology of aquatic crop lotus root, specifically a kind of double cropping cultivation method of lotus root. Background technique [0002] In most of the lotus root planting areas in my country, the method of planting lotus root once and harvesting fresh lotus root for one season is still used to produce lotus root. This cultivation method can only harvest a crop of fresh lotus root in a growth cycle of lotus root, generally only can plant and harvest once in a natural year, and its lotus root field utilization efficiency and lotus root production efficiency are all very low. For the warm climate in South China, this cultivation method can be planted twice a year, and fresh lotus root can be harvested twice. Lotus root can be planted in mid-June and harvested in late July. Although the utilization rate of the lotus root field has been partially improved like this, and the output of the lotus root ha...
