Planting conditions of Amomum villosum

Amomum villosum may not be heard of by many people, it is alias cardamom, it is a kind of condiment, but also a kind of medicine, it is very popular in some areas, and it is also cultivated in various parts of our country. The planting benefit is good, many people want to plant it, but it has certain conditions for the planting environment, let's take a look at the planting conditions of Amomum villosum.

1. Temperature requirement

Amomum villosum is a typical tropical and subtropical rain forest plant, which likes a warm and cool environment, and temperature has a great influence on its growth and flower bud differentiation. It is suitable for growth when the annual average temperature is between 22 and 28 degrees, and grows slowly between 14 and 19 degrees, and can withstand the low temperature of about 0 degrees for a short time. In winter, the monthly average temperature is required to be above 12 degrees, otherwise its flower buds will not sprout, the higher the temperature, the faster its flower bud differentiation, but also can blossom in advance and increase yield. Flowering temperature should be above 22 degrees and below 30 degrees, too high and too low will affect flowering.

2. Moisture requirements

Amomum villosum likes humid environment and is afraid of drought and stagnant water environment, so it is suitable to be planted in areas with annual precipitation of more than 1000 mm, and the yield is the highest in precipitation of 1400 mm. It is suitable to grow at a relative humidity of more than 80%, but if the soil moisture is too much, it will affect the respiration of the roots and easily cause rotten roots. In the flowering period, the humidity requirement is very high, the air humidity should be more than 80%, and the soil water content is 35%. Only in this way can we ensure the flower opening and stigma vitality, which is conducive to pollination.

3. Lighting requirements

Amomum villosum is a shade plant, which needs weak light environment when growing, avoid strong light exposure, and need certain light when growing at the seedling stage, but strong light will cause young trees to wither, so it is appropriate to do a good job of shading and maturing, with a shade degree of 70% and 80%. If the shade exceeds 80%, the plant growth is weak and the ramet decreases, but the shade is less than 30%. Under strong light exposure, the plant growth is dwarfed, the leaves are withered and yellow, and they are also vulnerable to freezing damage in winter.

4. Soil requirements

Amomum villosum is a perennial plant, which consumes a lot of nutrients every year, and it is also a stolon densely covered with ground, so it is not convenient to loosen the soil when planting, coupled with shallow roots, afraid of drought. Therefore, the requirements for soil are more strict, and it is appropriate to choose sandy loam soil with deep soil layer, loose and fertile soil, rich in humus and strong water and fertility conservation. Although sand and clay can also be planted, it is necessary to do a good job of fertilization before planting, mainly organic fertilizer, with appropriate amount of nitrogen, phosphorus and potassium fertilizer and trace elements.
