First, the introduction of varieties
Figs are divided into four categories according to their pollination relationship and flower type. The figs cultivated in China are all common types. Here we focus on the recommendation of two fine varieties
.
1. Brancico is native to France. This species is less fruitful, mainly in autumn fruit. Summer fruit is inverted conical, mature yellow-green, single fruit weight 100 ~ 140
Grams. Autumn fruit is inverted conical or obovate, generally weighing 40 to 60 grams, ripe yellow-green peel, the top of the fruit does not crack, pale pink flesh. The variety contains sugar
The amount is high, the mature fruit contains 18% to 20% sugar, and the meat is fine, sweet, and of high quality.
This species grows in the middle and opens its tree. Strong branching habits, strong unisexuality, and high yield. In the middle of March in Chongqing, it sprouted in mid-November.
Leaves, flowering gradually from May to July. Summer fruit matures in mid-July, and autumn fruit matures from mid-August to mid-October. The varieties have strong salt and cold resistance
It is suitable for development in the vast area south of Beijing.
The variety has moderate fruit size, good quality, and excellent fresh food processing. Adaptability, extremely cold, good yield, it is worth a large area development.
2. Masi Toufen is native to California, USA. The results of the summer and autumn are two times, but mainly autumn fruits. The summer fruits are oval, larger and the average fruit weight.
100 ~ 150 grams, green purple skin. Qiuguo inverted conical, medium and large, the average fruit weight 80 to 100 grams, purple brown when mature. The variety of fruit is big and fruit
Bright skin, peach pink, slightly thicker meat, sugar 16% to 18%. The fruit has good commercial properties, and the peel has high toughness, is more resistant to storage and transport, and is particularly resistant to disease.
The trunk is not obvious, the tree vigor is medium, the branches are more open and the crown is smaller, suitable for dense planting. Easy branching, multiple branches, large amount of growth, strong unisexuality, easy to
result. The year of planting was high. The period of natural dormancy is not obvious, and the specific time will vary depending on the temperature of the earth. Natural leaves will be less and the leaves will dry after frost.
The rear began to fall off. In mid-March to mid-August, Xiehua was completed in Chongqing, Xiaguo matured in early July, and Qiuguo entered successive stages from late August to mid-October.
Cooked. Fallen leaves in late November. The variety is suitable for development in the Huaihe River, the Yangtze River basin and its south.
This variety is exceptionally strong in disease resistance, wide in adaptability, high in yield, good in quality, resistant to storage, and has great development potential.
Second, build gardens and planting
1. Fig has strong adaptability to the environmental conditions and the requirements for the establishment of figs, the root activity temperature is above 10°C, and the spring daytime temperature reaches 15
The germination starts when the temperature is above °C, and the optimum temperature for the growth and development of shoots is 20-30°C. Generally speaking, the average annual accumulative temperature of 5°C or above is 4800°C.
The growth of figs and the results are most advantageous. The figs do not impose strict requirements on rainfall. The annual precipitation is in the range of 400-800 mm. The growing season (from April to October)
Precipitation in areas between 90 and 270 mm is suitable for the growth of figs. The figs have a wide range of adaptation to the soil, but in sand and loam
The best growth (see Table 5). Fig is very tolerant to salt and alkali (tolerance 0.3% to 0.5%) and is an ideal fruit tree species for the development of saline-alkali land. Fig,
It is better to have a soil pH of 7 to 7.5 (see Table 6). The overall requirement is that the soil is rich in fertilizer and has good drainage.
