Bulbous Flower South Africa Bethlehem Star Large-scale Planting Technology

How to grow the Star of Bethlehem in South Africa? With the advantages of simple cultivation, less labor, quick effect and remarkable benefit, Yuanjiang County of Yunnan Province has been carrying out bulb propagation and cut flower planting in Yuanjiang County of Yunnan Province in recent years. The following experts will introduce the planting of Bethlehem Star in Yuanjiang County, Yunnan Province, South Africa as follows.

1 planting site selection

1.1 planting site and soil

The origin of Bethlehem Star in South Africa is naturally distributed in the alpine gravelly exposed hillside areas, like well-drained soil, poor drainage will make the bulb rot. Therefore, the planting land should choose sandy land with good drainage, even if the soil fertility is poor, but because of the good drainage capacity, if one-time application of organic fertilizer or slow-release fertilizer before planting, high-quality products can be produced. The South African Bethlehem Star planted in Yuanjiang requires that the soil has excellent drainage, preferably in sandy loam and sandy soil, because the bulbs rot easily if they are overwatered. Bulb rot can occur from 3 leaves after seedling emergence to flowering period. generally, when the leaves are withered or wilted, the underground bulbs begin to rot, and it is necessary to pull out or control watering in time, but it is often too late when this happens, so the site selection before planting is very important.

1.2 Lighting

The Star of Bethlehem in South Africa likes places that are leeward and sunny and can receive all-day sunshine in winter. In spring and summer, usually strong sunlight from April to August accompanied by high temperature will burn inflorescences and affect the commercial nature of cut flowers, so the flowering period should be covered with a 50% sunscreen.

1.3 temperature

The Star of Bethlehem in South Africa likes a warm environment, a rainy summer and a cold and dry winter. When dormant in winter in its place of origin, it must be in a dry environment and can withstand a low temperature below zero, so the planting land should choose frost-free areas to avoid dormancy due to long low temperature growth cycle or low temperature. In Yuanjiang hot dam area, the bulb showed no dormancy period from March to November. Cut flowers could be harvested as soon as 50 days after bulb planting, but most of them were about 80 days. After harvest, the bulbs continued to divide into 2-3 bulbs until they grew into flowering bulbs. When the temperature is higher than 25 ℃, the bulb continues to grow and blossom, which is completely different from that planted once a year in high altitude areas such as Kunming. Annual flowering and rapid propagation of bulbs in summer can be achieved by planting in Yuanjiang.

2. Land preparation and planting

2.1 Land preparation and border-making

The planting land is turned deep above 30cm, raked flat after drying, the width of the border is 0.8m ~ 1m, the width of the furrow is 30cm, the height of the border is about 25cm, in the area with more Rain Water, the border is slightly higher, it is necessary to make a border surface with good drainage.

2.2 planting density and depth

The bulb of Bethlehem Star in South Africa is a perennial underground bud, and the scale is the base of the leaf, which is most afraid of waterlogging. The bulb is shallow and about 5cm, and its growth and flowering performance is the best. Therefore, the planting depth is about 3 ~ 5cm, and a small part of the bulb head is exposed during planting. The row spacing was kept between 15 and 20cm, and 8000 to 10000 balls per mu were planted. If the plant is too deep, not only the flower will be late and the flower stem will be short, but also the risk of bulb rot will be greatly increased.

2.3 Water and fertilizer management and grass control measures

The star of Bethlehem in South Africa needs medium fertility fertilizer. Slow-release fertilizer is used as base fertilizer when planting, and then foliar fertilizer with high phosphorus and potassium is sprayed every 3-5 days.

After planting, water until the soil is moist, and immediately seal the soil with the pre-budding herbicide Acetochlor. During the growing season, keep the soil moist and avoid overwatering. Otherwise, it is very easy to cause the seed ball to rot. When the leaves begin to yellowing, the bulbs no longer grow, reduce the amount of water or stop watering. During the growth period, if there are too many weeds, the selective herbicide can be sprayed or quinofop can be controlled.

3 harvesting and packaging

The star of Bethlehem in South Africa can be harvested 75-100 days after planting, and the time is mainly determined by the size of the bulb, the length of the dormant period, climate and growth environment. The fast one can be harvested more than 50 days after planting, while the slow one takes 5 months. Generally, the plant begins to produce flowers and arrows when it grows 8 leaves, and the harvest is best when the inflorescence just has 1 or 2 buds blooming, when the buds of cut flowers open the most, and the cut flowers can be cultured in water for more than 15 days. Harvest should be carried out in the morning as far as possible, and be handled gently during harvest to avoid breaking the flower head. After harvest, the cut flowers of the same specification are bagged by grades and tied with a rubber band for every 10 pieces.

4Regulation of puerperal period

The Star of Bethlehem, South Africa, dormant in winter in its origin, can withstand a low temperature of less than 0 ℃. Bulbs can be preserved underground in dry areas, but not in damp and cold temperate regions. Generally, 2 months after flowering, the leaves can dig balls after storing sufficient nutrients. If Rain Water has too many bulbs and the bulbs rot, the bulbs can be dug out after picking flowers to keep the leaves shady and dry, so that nutrients return to the bulb. After the bulb is dug up, it should be stored in a frost-free place without cold storage. generally, the residual leaves are removed and placed in a cool and ventilated place. the bulbs will naturally release their sleep after about 2-3 months, and then be replanted the following spring. In tropical and subtropical regions with warm climate, the delivery period can be adjusted according to the market demand, just put the seed ball in a cool and ventilated place, if the seed ball needs to be preserved for a long time, the seed ball can be placed in the cold storage, the temperature can be adjusted at about 15 ℃, and then it can be planted and listed in batches.

The environmental requirements of bulb flowers, as well as the methods and matters needing attention of planting bulb flowers.

There are many kinds of bulb flowers. Do you like planting bulb flowers? do you know the planting method of bulb flowers? how to plant them in the end, so that bulb flowers can produce gorgeous flowers? what are the specific requirements of bulb flowers for the environment? let's get to know it together.

Temperature

Most bulb flowers like to grow and develop at low and medium temperatures, and dormant at high temperatures, such as tulips, daffodils and hyacinths. Most bulbous flowers need a certain period of low temperature in the bulb state or plant state before they can germinate and differentiate.

Moisture content

Most bulb flowers are native to hillsides, so they like to grow in well-drained soil. some bulb flowers grow well in water or wet soil, such as irises, water taros, daffodils, hyacinths and so on.

Light

Most bulb flowers need plenty of sunlight, such as gladiolus, canna, freesia, tulips, irises, evening jade, lilies, calla lilies and so on.

Soil

Most bulb flowers prefer loose soil, and they grow poorly in too clayey soil, especially for bulb expansion. The pH value of soil is mostly between 6.0 and 7.0.

Fertilizer

Bulb flowers need nitrogen fertilizer to promote leaf growth and photosynthesis; phosphorus fertilizer to promote robust root growth; potassium fertilizer to promote stem firmness, enhance stress resistance and disease resistance, and promote bulb expansion. However, fertilizer is generally required less than other flowers. However, some cut flower species which have been cultivated and domesticated for a long time, such as Tang Jupu, Dahlia and so on, need a lot of fertilizer.

The above is about the planting method of bulb flowers, through the study of this article, how much do you know? please continue to follow the succulent flower bed and learn more about it.
