A kind of leek cultivation technique

Abstract

The invention relates to the technical field of vegetable planting, in particular to a fragrant-flowered garlic cultivation technique. The cultivation technique comprises the following steps of seedling cultivating and field planting, and the seedling cultivating comprises the following steps of preparing a seedbed, selecting a variety, adopting a drilling method, and keeping a matrix wet before seedling emerging and after the seedling emerging. The field planting comprises the following steps of preparing a field planting groove, conducting processing before seedling planting, and adopting a soilless cultivation method. The plant diseases and insect pests of fragrant-flowered garlic roots are completely eradicated, it is completely guaranteed that the population density of bradysia odoriphaga in the whole growing period is 0, a small part of rootstocks are placed in a small-type field planting cup with small ceramsites, upright ventilation and upper portion growth of plants are conveniently supported, picking is convenient, the traditional single-layer planting mode is broken through, the space utilization rate is improved, nutrient solutions between the upper layer and the lower upper circularly flow, the dissolved oxygen in the nutrient solutions is greatly increased, the uniformity of the nutrient solutions is improved, the optimal root environment is provided for the fragrant-flowered garlic root systems, and the roots can conveniently absorb elements in the nutrient solutions.

Description

Technical field [0001] The invention relates to the field of vegetable planting technology, and more specifically, a leek cultivation technology. Background technique [0002] Leek is a perennial plant of the genus Allium in the Liliaceae family, native to China. It is rich in nutrients, the leaves, flower moss and chive flowers can be eaten, and it is rich in vitamins, minerals, carbohydrates and protein. At the same time, the volatile oil of leek, the main component of which is sulfur-containing compounds, has a special pungent fragrance, which can increase appetite, promote metabolism and gastrointestinal motility, and has a certain health effect and medicinal value. During the production of leeks, they are often damaged by pests and diseases. In particular, larvae maggots damage the main pests of leeks and become the main factor restricting the development of leeks. The following methods have big problems and defects. [0003] At present, various control measures such as roo...

Problems solved by technology

[0003] At present, various control measures such as root irrigation with pesticides, sweet and sour solution trapping and killing adults, nicotine ricinoleic acid, and crop rotation are mainly used. The pesticide residues are often large, and frequent application of pesticides is required, and there are great food safety hazards; Due to the influence of the environment and facilities and equipment conditions, the control measures are lagging behind, and the production is very passive; and the overall effect is not good, and it is labor-intensive and time-consuming, which cannot fundamentally solve the harm of leek root diseases and insect pests. Food height is 20-25cm
