A Crop Rotation Model of Cut Flowers Oriental Lily and Medicago

Abstract

The invention discloses a crop rotation cultivation mode of cut flower oriental lily and alfalfa. Under the condition of solar greenhouse, the crop rotation cultivation mode includes lily cultivation in August of the first year to February of the second year and March to June of the second year. The steps of alfalfa cultivation and lily cultivation are as follows: a. Fertilize the soil to make a border; b. Water and shade; c. Plant the bulbs of lily bulbs upwards; d. Water once after planting to keep moisture , nutrient, light, temperature and humidity; e, harvest when lily buds are colored; f, prepare the soil stubble for use; alfalfa cultivation steps are: g, soil preparation and furrow; h, sowing or drilling; i, irrigation immediately after sowing Once, keep water, nutrients, intertillage and weeding; j, chop up the stems and leaves of the yellow alfalfa in the field, plow and return to the field, after plowing, water 10cm-15cm, retting for 30d-40d, and prepare for the next lily planting. The invention can improve the soil physical and chemical conditions in the greenhouse and produce high-quality cut lily products.

Description

technical field [0001] The invention belongs to the technical field of crop rotation cultivation, and in particular relates to a crop rotation cultivation pattern of cut flowers oriental lily and alfalfa under the condition of a solar greenhouse. Background technique [0002] The use of solar greenhouses for crop cultivation is not only efficient but also annual production is the main means and needs of modern high-efficiency agriculture and material civilization. However, the development of a solar greenhouse requires a large investment. Once it is built, it can only be planted in the same place year after year. At the same time, due to its immobility and the high temperature and high humidity environment in the greenhouse, problems such as soil degradation are becoming more and more serious, resulting in an increase in pests and diseases. , The growth of plants is weak and the quality is declining. Flower farmers can only choose to rebuild facilities in different places or...

Problems solved by technology

However, the development of a solar greenhouse requires a large investment. Once it is built, it can only be planted in the same place year after year. At the same time, due to its immobility and the high temperature and high humidity environment in the greenhouse, problems such as soil degradation are becoming more and more serious, resulting in an increase in pests and diseases. , the growth potential of plants is weak, and the quality declines. Flower farmers can only choose to rebuild facilities in different places or choose other industries. This not only increases investment but also affects farmers' enthusiasm for production, and seriously restricts the development of high-efficiency facility industries.

[0003] The conventional crop rotation mode of solar greenhouses in cut flower production areas is mainly a single "flower + flower" or "flower + vegetable" planting mode. Farmers simply arrange crops blindly based on their own habits and markets, and do not pay attention to crop rotation and soil fertilization and improvement. , which aggravates the soil continuous cropping obstacles and degradation in solar greenhouses to varying degrees

Disadvantages of the conventional crop rotation mode: (1) The soil in the greenhouse is seriously degraded, with poor physical and chemical properties, which is not conducive to plant growth; (2) Long-term continuous cropping, serious production obstacles and serious pests and diseases, the quality of cut lily products is low, the flower buds are easily aborted, and the flower diameter is small , thin stems, etc.
