Despite the varying levels of love for cigarettes, the passion for growing cigarettes remains constant. As an adaptive plant, cilantro can theoretically be grown in four seasons a year. However, for harvests and yields to be high, attention must be paid to the effects of temperature on the growth of fragrances. The following are some suggestions for your information on the timing and methods of fragrance cultivation:
01 best planting time
Quarterly cultivation differences
Cussava can be grown over four seasons, but harvests and quality vary significantly from season to season. It is generally recognized that spring, march-april, and autumn, september, are the best planting time for spices. At this point, the temperature is moderate, at about 15-20°c, and meets the best conditions for the growth of fragrances。
The effect of temperature on growth
If the temperature is below 15 °c, the budding rate of the fragrance seeds is reduced and slow to grow and the seed is small; and if the temperature continues to be higher than 20 °c, the fragrance leaves are over-growing, obese and dim. In hot summers, if temperatures exceed 30°c and no shades are taken to cool, cuisine may die from high temperatures and cannot be harvested。
02 open planting techniques
Water the three steps
Water is crucial when fragrance is grown in the open. The “three-water seedling” principle needs to be followed to ensure proper watering and soil moisture during each critical period. First-time water is required in order to ensure that seeds are closely integrated with the soil and that sufficient moisture is provided for its seedlings; to keep the soil wet before seeding and avoid drying affecting the seedlings; to pour a slow seed water once the seedlings have grown so as to stabilize the roots of the small seedlings; and to re-water the leaves to promote their growth when they reach a height of 5 cm。
Fertilizer and shade
Fertilizing is also an inexorable link. It is recommended that a combination of 15 to 10 and 20 per cent of potassium nitrogen phosphorus be used and distributed in two stages: the first time when a small seedling grows to 3 to 4 leaves, the second time when the seedling is about 8 cm high. In summer, sun shades are required to protect against high temperature damage and, if necessary, to build a sunscreen net to shield about 60 per cent of the sunlight from direct solar activity and high temperatures。
Gyroculture techniques
Seeding and temperature protection measures
Cultivated inside the shed, the option is to plant dry seeds directly in late september, requiring approximately 2. 5 kilograms per acre. It is imperative that, before winter, frozen water be poured in order to increase the resistance of spices to cold temperatures. A 2-centimetre-heavy straw was then laid on the ground to provide the required temperature protection for the root of the cuisine。
Temperature control and nutrient accumulation
In mid-january, when the shed was covered with thin film, the temperature was carefully regulated. Different temperatures should be regulated during the day and night to ensure normal growth and nutrient accumulation. The temperature of 20-25°c should be maintained in the shed during the daytime period in order to facilitate the full acceptance of fragrance and the accumulation of nutrients. At night, the temperature is reduced to 10-12°c, reducing unnecessary nutrient consumption. In the event of a dark day, the temperature is maintained at about 15°c to ensure that the normal growth of the spices is not affected。
04 soil preparation and soil rehabilitation
Soil stratification
In order to ensure the healthy growth of spices, we need to prepare the soil carefully. Soils should be treated in layers to achieve optimal results: at the bottom, 20 centimetres of soil can be mixed with decomposed cow manure to increase soil fertility; at the middle 15 centimetres of soil can be mixed with biobacterial fertilizers to promote the strong growth of the fragrance root system by adding different fertilizers and materials to the layer; and at the top 5 centimetres of soil, a layer of neptite can be laid that preserves both water and is well ventilated, thus preventing water from evaporating too quickly。
Drainage design and seed treatment
It is proposed to set the width of the oscillation at 1. 5 m and to raise slightly the middle of the oscillation to form the shape of the "back of the turtle" so as to facilitate the smooth flow of water. At the same time, drains are dug on the edges of the plume to ensure that the water is drained in time to avoid the plume. Prior to planting, the fragrance seeds were immersed in warm water at 50 °c for 20 minutes for fungicide treatment, followed by drying and mixing with sand at a scale of 1:5。
The timing of the harvest of 05 cuisine
Time and conditions of harvest
At temperatures ranging from 15 to 25°c, it takes approximately 28 to 32 days from sowing to harvesting. Maintaining temperature increases the frequency of harvests. When the cuisine is about 25 cm high and the weight of a single tree is 8 g, it can be harvested in batches. At the time of harvest, two centimetres of roots would be retained, so that new seedlings could also emerge next to them, thereby increasing the number of harvests. In the event of chronic cold weather, the fragrance will slow down and may take 45-60 days to harvest。
Overall, the planting of cilantro is not complicated. A rational planting plan based on the local weather and planting environment would yield successful harvests。
