The environmental conditions required for fruit mulberry cultivation
In addition to determining its own genetic characteristics, the growth of the fruit mulberry is carried out under the following environmental conditions: soil, light, moisture, air, temperature and other factors.
{1}Soil: Soil is the place where fruit mulberry lives, and various kinds of substances needed for fruit mulberry are taken in from the soil. So the physical structure of the soil and the fertility of texture can affect its growth and development. Strong resistance and adaptability, so all kinds of soil can be planted, but different soil has different effects on the growth of fruit mulberry, so its output is not the same. Generally loam. Sand loam suitable for fruit mulberry growth. Its adaptability to soil pH is relatively strong. Normal PH values ​​can grow normally within the range of 4.5-9, while neutral soil is the most suitable. Clay can be loosely improved by deep turning. Sand can be improved by growing green manure between rows and increasing soil fertility. According to the practice of us and the introduction of planting units, it has been proved that planting in the slopes of the arid and semi-arid loess plateaus in Beijing, Gansu, Ningxia, and northern Shaanxi, and in the western Maowusu sandy land and the subtropical Qinba mountainous areas have achieved great successes above 45 degrees.
{2}Light: The fruit is a genus positive plant, when the light is sufficient, the chlorophyll content is high, the leaf color is dark green, the dry matter is accumulated more, the fruit is large, the quality is good, the yield is high, the drought resistance, the cold resistance, the disease resistance is enhanced, so in fruit Mulberry planting and pruning should pay attention to reasonable dense planting. Cropping appropriate {mu 8,000 sticks stay}, that is to make full use of light energy, but can not make the group too dense.
{3} Temperature: Germination of fruit mulberry, branching and flowering. The results should be carried out under certain temperature conditions. When the temperature is above 5 degrees, the absorption of roots is strengthened. When the temperature is above 10 degrees, the root system begins to grow, and the temperature is above 12 degrees. When the shoots are sprouted, cell division is accelerated at 25-32 degrees Celsius, and growth is inhibited at temperatures above 40 degrees. At this time, if the water is sufficient, the high temperature hazard can be mitigated. When the temperature is lower than 12 degrees, the deciduous leaves of the fruit mulberry dormancy, and the roots and shoots Increased sugar content, thus improving the cold resistance of the fruit mulberry, therefore, China's northwest region can still normally winter at -30 degrees.
{4} Moisture, etc.: The effect of moisture is self-evident. However, the annual rainfall can be planted in areas with a diameter of 500 mm or more, and the frost-free period is preferably over 100 days.
{5} Air: The fruit mulberry is flowering and firm, with the wind as a medium, the breeze can promote the transpiration of the mulberry tree and reduce the humidity. Therefore, the branches should be reasonable and dense, so that the air can circulate.
