Hydroponic method of jute

Abstract

The invention discloses a hydroponic method of jute, belonging to the technical field of crop cultivation. The method comprises the steps of: taking a plastic cultivating box with the length of 32cm, the width of 22cm and the height of 7.5cm as a cultivating container, filling hydroponic nutrient solution into the cultivating container, enwrapping the base of a seedling by a sponge strip, fixing the base of the seedling in a small hole of a foam plate by a pair of tweezers for cultivating under proper cultivating conditions. In the invention, the method is simple, the cost is low, the survival rate of the seedlings is improved to 100%, the average height of the seedling can be 10cm after transplanting seedlings for half of a month, the raw weight of ground part of the seedling is about 0.5 g/strain, the complete, healthy, clean and orderly root system can be obtained, and the difficult problems of lost root systems and polluted samples in the traditional method of soil culture can be overcome.

Description

1. Technical field [0001] The invention relates to a jute hydroponic method, which is specially used for jute hydroponic cultivation. It belongs to the technical field of crop cultivation. 2. Background technology [0002] Jute (Corchorus capsularis) has another name called network hemp and green hemp. It belongs to Tiliaceae (Tiliaceae) jute (Corchorus) annual herbaceous bast fiber crop, 2n=2x=14, and belongs to diploid plants. There are many species of the genus Jute, and two species with cultivation value are round fruit species jute (Corchorus capsularis L.) and long fruit species jute (C. olitoriust L.), which are collectively referred to as jute. Jute is a dicotyledonous short-day self-pollinated plant, with a plant height of 3-5 meters, a cylindrical stem, and a base stem diameter of about 1.5cm. The stem color is mainly red and green, and the tap root system; Round or lanceolate; fruit is a capsule. Jute is one of the cheapest natural fibers, second only to cotto...

Problems solved by technology

[0004] 1. On the one hand, the complete root system cannot be recovered from the plant samples of the soil culture medium, and the part lost in the medium is precisely the young root tips and root hairs where protein synthesis is the most active. pollution, and is also not conducive to ventilation

[0005] 2. Although the root system obtained by sand culture medium is more complete than soil culture, there will still be a small part of young root tip and root hair loss, and the root system grows in the sand, it is difficult to maintain nutrition and ventilation, the root system is easy to rot, and the survival rate is low. It is difficult to obtain uniform seedlings, and it is also easy to cause experimental contamination

[0006] Therefore, adopting soil culture substrate culture and sand culture substrate culture to obtain jute root material will inevitably bring a lot of trouble and high cost. Therefore, how to establish a jute hydroponic method with high throughput, high repeatability and low cost, in Obtaining a large number of complete and healthy jute seedlings and root materials in a short period of time, and applying them to the identification of jute salt tolerance and root proteomics research, has become an urgent problem to be solved by scientists in this field
