2. Strengthen Soil Fertility Management Before planting seedlings in the ditch, apply 4t (tons) per 667m2 (mu) of high-quality ring fertilizer, 100kg of urea and 100kg of superphosphate. At the end of the second year after planting, there was a deep fall between the lines. In 2 years, the whole park was overturned. In combination with deep turning, each 667m2 (acre) applies 2t (ton) of fertilizer, 100kg of potassium sulfate compound fertilizer, 1000kg of wheat bran or weed, and 50kg of urea. In mid-March each year, 50kg of urea is applied per 667m2 (mu); during the expansion period of Chunguo, Xiaguo and Qiuguo (late May, early July and early September), fertilizers are applied once every 667m2 (mu). ) Top 40kg of potassium sulfate compound fertilizer. The base fertilizer is applied once every two years in mid-October and 2500 kg of fertilizer is applied every 667m (mu). In combination with spraying, 0.3% potassium dihydrogen phosphate is sprayed 3 to 4 times a year. Irrigation with top-dressing, summer drainage and flood prevention, winter water should be poured in late October. In addition, after 1 to 5 years after planting, the trees were covered with grass. After the 6th year, the whole park was covered with grass (covering 20cm thick wheat straw, weeds, leaves, and peanuts, etc.). At the end of autumn, the grass was buried under the combined application of fertilizer.
3. Reasonable intercropping After the first two years of planting, strawberry was intercropped between orchards. It was planted in mid-September each year, and 667 to 20,000 plants were planted in 667m2 (mu). The winter mulch was covered, and 1500 to 1800 kg of strawberries were harvested in April of the following year. In the third year, we planted watermelons, and watermelons were harvested as radish. Peanuts in the 4th and 5th years. It is forbidden to intercrop high-stalk crops such as wheat, corn, soybeans and cotton.
4. Reasonable pruning The pruning using sparse layer sparse crowns is practiced every year in early March. Colonization was made at the location of 40cm in the same year, and 3 to 4 shoots of 80~150cm in length were germinated under the excision, and the upper branch was selected as the central leading cadre. Three branches with appropriate orientations and angles were selected as the main branch and the first branch was established. The buds below the main branch were all removed. In the second year, branches with three directions and the main branches of the first layer were selected from 100 cm away from the main branch of the first layer and used as the main branch of the second layer. In the third year, two relatively horizontal branches were selected as the main branch of the third layer at a distance of 80 cm from the main branch of the second floor, and the extension branch of the central leading branch was cut off (falling head). In the fourth year, the shaping was basically completed.
5. Control pests and diseases Less fig pests and diseases, but there are spider mites, longhorn beetles, and keratoses occurring in the gardens near apples and pears. Can be sprayed on the red spider 15% broom net 1500 times liquid or 20% dying net 200 times liquid; on leaf spot can be sprayed 68% of bacteria rust enemy wettable powder 1500 times or 50% thiophanate-methyl 1000 times liquid prevention and treatment; for Tianni cattle can be used to infuse omethoate 10 times liquid or dichlorvos 100 times liquid plug holes for prevention and treatment.
6. Timing of timely harvesting and cold-proof figs is appropriate from mid-June to October, depending on the product's different uses. The foreign trade should be harvested when it is cooked at eight or nine hours; the local sales should be split with small holes in the top of the fruit, and it is advisable to harvest when the peels are clearly visible on the Internet. Harvest time is better when the morning and evening temperatures of sunny days are relatively low. Take care to handle it gently and try not to scratch or tear the peel. During the first 1 to 2 years after planting, the young fig trees are most afraid of frost damage. For this purpose, strawberries are inter-row between the rows. The first is beneficial to the trunk soil (3cm in height) before the light snowfall; the second is that the strawberries cover the mulch prior to winter and can increase the temperature of the ground. , to ensure soil moisture content. In addition, a height of 1.5m, corn-straw, etc., is erected at a height of 1.5m in the garden every 8m to ensure that the fig is free from freezing damage. 3, 4 year old fig tree, winter trunk stems tied grass to prevent cold.

High-yielding Cultivation Techniques of Fig Ficus in Hilly Land
1. Good seedlings and strong seedlings, carefully planting Bran Rake varieties that are more productive and stable. Before the planting, dig 1m in depth and 2m in width, apply enough base fertilizer, and fill with water after backfilling. Choose high seedlings with a height of 1m or more and a root thickness of 2~5cm or more, and soak the seedling roots in water for 24 hours before planting. In mid-March (the temperature is stable above 10°C) digging and planting. After planting, fill in enough water, and then raise the soil to the root and neck position of the seedlings. Then all the seedlings will be wrapped with the mulch (released after budding) and covered with the trunk as the center. 1m2 mulch. The survival rate of seedlings can reach 99.3%.
