How to pant seeds
1.Seed soaking. (Very little seeds need not do it.)Please put the seeds in the water for about 12 hours.The temperature of the water is about 20 to 25 degrees celsius.
2.Sow seeds. Make some fecund and soil.Water it and keep it moist.Put the seeds on the soil evenly.
3.Cover soil. (Very little seeds need not do it.)Soil thickness is anout twice as the size of the seed.
4.Water it. Keep water it one time every day,which had better do it at night,but you should not water too much.7-15 days latter,it will be burgeon.
Hi warm climate. Strict requirements on the soil, but well-drained sandy soil cultivated good clip, when live, with Ren Chufen water mixed with ashes mixed, then sow the seeds uniformly gray, slightly Gaiyan seed, practical and irrigated, Usually when the temperature 15-20 degrees, 10-15 days to emergence.
The growth and development of orange fruit trees and flowering results are closely related to environmental conditions such as temperature, sunshine, moisture (humidity), soil and wind, altitude, topography and aspect. The most important influence of these conditions is temperature. Even temperatures with a difference of 0.5 °C sometimes have very different results. The growth and development of orange fruit requires a temperature of 12.5 to 37 °C. In the autumn flower bud differentiation, the temperature of day and night is about 20 °C and about 10 °C, and the soil temperature of root growth is about the same as that of the aboveground part. Too low temperature will cause the orange fruit to be frozen, sweet orange -4 ° C, Wenzhou mandarin -5 ° C will cause the leaves to be frozen, sweet orange below -5 ° C, Wenzhou mandarin below -6 ° C will frostbite large branches and branches, sweet orange Below -6.5 °C, Wenzhou mandarin below -9 °C will freeze the plants.
Slightly shade-tolerant, warm and humid climate, not cold-resistant, when the temperature is below -8 °C, freezing damage occurs, suitable for deep and fertile neutral to slightly acidic sandy loam.
High temperature is also not conducive to the growth and development of citrus. When the temperature and soil temperature are higher than 37 °C, the fruit and roots stop growing. The effect of temperature on the quality of the fruit is also obvious: in a certain temperature range, the sugar content and the soluble solid matter generally increase with the increase of temperature, the acid content decreases, and the quality becomes better.
Citrus is a tree species that is more resistant to negatives, but it still needs good sunshine for high quality and high yield. Generally, the areas with annual sunshine hours of 1200 to 2200 hours can grow normally. For example, in South China, where the sunshine is good and the heat is abundant, compared with the Chongqing citrus production area with less sunshine, the fruit has high sugar content, low acid content and high sugar-to-acid ratio.
Tropical and subtropical regions with an annual rainfall of about 1000 mm are suitable for citrus cultivation, but irrigation is often required due to uneven annual rainfall distribution. The relative water content of the soil is suitable for 60%-80%. If it is less than 60%, it needs to be filled with water. If there is too much rain, it will cause water accumulation in the soil or high groundwater level. The poorly drained citrus orchard will cause the roots to die. Citrus fruit trees require a relative humidity of about 75%.
Citrus adapts to the soil in a wide range, purple soil, red yellow soil, beach and sea coating, pH 4.5 ~ 8 can grow, with a pH of 5.5 ~ 6.5 is most suitable. The citrus root growth requires high oxygen content, the soil texture is loose, the structure is good, the organic matter content is 2% to 3%, and the well-drained soil is most suitable.
