Embodiment Construction

[0024] 1. Land preparation

[0025] Each batch of sunflowers is deeply plowed with a rotary tiller before planting. Deep plowing is conducive to the growth and absorption of deep nutrients for sunflowers. Break the sunflower stalks during deep plowing, return the sunflower stalks to the field as much as possible, and apply decomposed organic fertilizers, complete the plots, and dry the ground.

[0026] 2. Seedling cultivation and seedling management

[0027] 1), Seed soaking and germination: Soak the seeds in warm water for 4-6 hours, keep the water temperature at 24-27°C, and let the seeds completely absorb the water. Then scoop up the seeds for germination. It is advisable for the buds of the seeds to show white spots before sowing.

[0028] 2) Sowing: Water the nutrient soil in the nutrition cup evenly before sowing, sow the seeds into the soil of the nutrition cup, cover with soil, and water after sowing. After sowing, stertin phosphorus is used to prevent the harm of m...

Abstract

The invention relates to a technology for full year cultivating sunflowers. The technology is characterized in that: a sunflower planting field is divided into 4 to 10 lots and a batch of the sunflowers are sowed for every 4 to 8 days, a same batch of the sunflowers are sowed in a same lot and sowing is carried out continuously in relays so as to realize continuous blossom of the sunflowers in four seasons of a whole year. The cultivating technology comprises the stages of soil preparation, sowing, raising of seedling, management of young seedling, transplantation, fertilizer and water management, disease and insect pests control, continuous cropping of the sunflowers, etc. The technology for cultivating sunflowers of the invention can not only realize continuous cropping of the sunflowers in a same lot in the south of China, but also realize planting in batches with a plurality of lots so as to incessantly providing high production sunflowers which have visual value for tourists everyday in four seasons of a whole year; therefore, the technology can meet the viewing and admiring demand of people and bring no environmental pollution, thus belonging to a green and environmental protection tourism technology.

Description

technical field [0001] The invention relates to a technique of continuously cropping sunflowers in the south, in particular to a technique of continuously cultivating sunflowers throughout the year, which is an innovation to the technique of cultivating sunflowers. Background technique [0002] Sunflower is an economical plant with high ornamental value, which is planted in many areas of our country. The main sunflower producing areas in China can be divided into one-season spring sowing areas and summer sowing multiple planting areas. The former is mainly distributed in northeast, north, and northwest areas with short frost-free period, drought, barren soil, and mild saline-alkali areas, where mid-maturing, mid-late maturing varieties or hybrids are mainly planted; the latter is mainly distributed in central, southern, and In areas with a long frost-free period and relatively fertile soil, such as the west and North China, early-maturing varieties or hybrids are mainly pla...
