Method for cultivating pigment marigolds in sand of high and cold region

Abstract

Disclosed is a method for cultivating pigment marigolds in the sand of a high and cold region. The method includes the steps that ground temperature rises and watering is sufficient 10 days before sowing; sowing is carried out on a fine day without wind, well-prepared soil is sieved by a sieve to cover a seedbed, a disinfectant is sprayed, a pesticide-clay mixture is scattered, and the seedbed is covered by straw; foliage top-dressing is conducted through DAP adding with water in the seedling stage, ventilation is achieved in a seedling growing greenhouse, films are uncovered, seedling exercising is conduced, seedling bacteria are sprayed so that damping-off can be prevented, soil insects can be trapped and killed by the way that phoxim is stirred and mixed with fried bran, and 200ppm of chlormequat chloride is sprayed for treating moderate seedling growth; compound fertilizer water is watered for facilitating growth, and the seedling age is 45-50 days for transplanting; field planting is carried out, the greenhouse is well built, soil preparation is completed, base fertilizer is fully applied, standard moisture in the soil is arranged according to the soil moisture width of 90cm, ponds are built on the water moisture surface in a twin-row mode according to the row spacing being 70cm and the line spacing being 60cm, film uncovering and seedling exercising are conducted 7 days before transplanting, and powder mancozeb is sprayed for disease prevention; field management is conducted, film rupturing and ridging are carried out, watering is achieved according to the dry and wet condition, diseased or infected plants are burned and buried, timber pile wires are pulled, the plants are fixed, and monopotassium phosphate is sprayed after defloration so that diseases can be prevented from endangering the plants. The method provides a mature technology for planting the marigolds in the sand of the high and cold region like Inner Mongolia.

Description

technical field [0001] The invention relates to a sandy land cultivation method of a pigment marigold in an alpine region. Background technique [0002] In China, most of the marigolds with good quality are planted in Yunnan, where the rainfall is abundant in the south, the temperature is 15-30°C, and the altitude is more than 1,600 meters. Crop competition for land is restricted by comprehensive development. In the area of ​​Tongliao Naiman Banner in the Inner Mongolia Autonomous Region, there are relatively loose land resources in the sandy area with an altitude of 350-450 meters, and pigment marigolds can be planted. Because this area belongs to the alpine climate, the rainfall is relatively small, and the soil temperature and humidity are relatively low. Both are low; there is no relatively mature planting technology at present. In order to make full use of the limited climatic conditions from April to October that are suitable for the growth of marigolds in this area, ...

Problems solved by technology

[0002] In China, most of the marigolds with good quality are planted in Yunnan, where the rainfall is abundant in the south, the temperature is 15-30°C, and the altitude is more than 1,600 meters. Crop competition for land is restricted by comprehensive development

In the area of ​​Tongliao Naiman Banner in the Inner Mongolia Autonomous Region, there are relatively loose land resources in the sandy area with an altitude of 350-450 meters, and pigment marigolds can be planted. Because this area belongs to the alpine climate, the rainfall is relatively small, and the soil temperature and humidity are relatively low. Both are low; there is no relatively mature planting technology at present. In order to make full use of the limited climatic conditions from April to October that are suitable for the growth of marigolds in this area, plant marigolds and add new varieties to the planting industry of farmers in this area. It is necessary to open up new channels for economic income, explore the planting technology of marigolds in low-altitude alpine regions, especially sandy land, and increase the resource supply capacity of lutein industrial production
