Low-yield fields and low-yield gardens account for a large proportion, which not only wastes precious light, heat, water, and land resources, but also requires continuous manual input. The fundamental reason for the extensive management is that the continuous cost of labor input is not proportional to the output, and there is a lack of material input and the introduction of science and technology. Therefore, changing the artificial input in hilly and mountainous areas and scientifically changing the planting mode are necessary conditions for gradually realizing large-scale agricultural production. Only by combining the climate characteristics of mountainous areas, laying out multi-level three-dimensional agriculture in mountainous areas, vigorously developing the production model of one-time planting and harvesting for many years, and striving to maintain and improve the ecological environment of mountainous areas, can we obtain ideal economic and ecological benefits.

Pomegranate trees are resistant to barrenness and drought, and wild leek varieties have the excellent characteristics of planting once and harvesting for many years. Wild leeks can generally be reserved naturally and have good market prospects. Wild vegetables can be further processed. In addition to traditional drying and pickling, irrigation, side dish products, wild vegetable juice and wild vegetable preservation products are also developed, which further increases the economic value of wild vegetables. improve.

Pomegranates are mainly cultivated with sweet pomegranates, and the main fine varieties are Dahongpao, Qingpitian, Baipitian, Hongpitian and so on.

Wild leek leaves, scapes and flowers are all eaten as vegetables; seeds, etc. can be used as medicine, which has the effects of nourishing the kidney, invigorating the stomach, refreshing, antiperspirant and astringent.

4. Prevention and control of pests and diseases and harvesting: timely control of pests and diseases and timely harvesting.

Example 2

1. Transformation of hilly dry land terraces in mountainous areas

1. Construction of water cellar

Make full use of the natural rain channels of hilly terraced fields in mountainous areas, and make improvements such as reinforcement and deepening, channel change and channel diversion, etc., in order to facilitate rainwater collection and irrigation. The water cellar is built in the corner of the terrace to collect rainwater. A rainwater sedimentation tank is installed in front of the water cellar, and a water outlet is installed behind the side of the water cellar.

2. Transformation of terraced fields

Reconstruction of terraced fields into wavy farmland is beneficial to rainwater collection, diversion, and water storage, and increases soil thickness and runoff time of rainwater to the soil surface, which is beneficial to crop growth.

3. According to the planting density of 70-110 plants per mu, excavate an inverted conical planting ditch (both as a flood diversion channel) with a row distance of 3m, with a width of 1m and a depth of 0.6m-0.8m. Excavate the tree hole, lay a layer of plastic mulch with a diameter of 0.6m-0.8m on the hard soil layer at the bottom of the hole, the area of the mulch film is 10-20cm larger than the tree hole, backfill mellow soil 10-20cm, and implement the anti-seepage and moisturizing technology of double film coverage , Try to make deep holes and shallow burials.

If the soil thickness is less than 0.6m, pomegranate trees are planted on the back of the ridge, and leeks are planted on the back of the ridge and on the side of the ditch; if the soil thickness reaches 0.6m, the pomegranate tree is planted on the back of the ridge and on the side of the ditch, and pomegranate trees are planted in the planting ditch .

Second, the cultivation of pomegranate

Pomegranates are mainly cultivated with sweet pomegranates, and the main fine varieties are Dahongpao, Qingpitian, Baipitian, Hongpitian and so on.

1. Before planting, turn the soil in the hole to the ground, deep plow and expand the hole, and mix in enough organic fertilizer. Lay a layer of plastic film with a diameter of 0.6m-0.8m on the hard soil layer at the bottom of the hole. The area of the film is 10-20cm larger than the tree hole to prevent rainwater leakage and facilitate the growth of lateral roots of the pomegranate tree. Backfill 10-20cm of mellow soil and then apply appropriate amount of compound fertilizer, try to achieve deep hole and shallow burial, dark water cultivation. After stepping on the ground, cover the tree hole with a second layer of plastic mulch to prevent moisture from volatilizing. After implementing the anti-seepage and moisturizing technology of heaven and earth double-membrane covering, try to make deep caves and shallow burials. The spacing between the rows of planting in patches should be 3 meters × 3 meters.

2. Configure the pomegranate as a pollinating variety for cross-flowering. The ratio of the main planting variety to the pollinating variety is at least 3:1. The above-mentioned varieties can be mutually pollinating varieties.

3. Appropriate late planting. Pomegranates are easy to pull out in early spring. Therefore, they should be planted when the ground temperature rises above 10°C in early April. After planting, the tree tray should be covered with plastic film to increase temperature and moisture, and shorten the seedling period. Improve survival rate.

4. Picking the heart to promote the growth of planting in July and August of the same year, carry out the topping to promote the branching and the growth of the lower part. After the rainy season arrives in July, control the water to prevent the branches from growing vigorously and prevent the branches from drying out in winter and spring.

5. Pomegranates should adopt the natural tree shape of clusters. The fixed stem height is 30-50 cm, and 4-6 main branches are issued. After 2-3 years of natural growth, the angle of the main branches is pulled to 55-60 degrees, and the basic shape can be basically formed. Pruning should be combined with winter and summer. The results of pomegranates are mainly leaf clusters with 6-8 good leaves. Therefore, in summer and spring, topping the inner branches, secondary branches and long branches to enrich the side buds and promote growth. branch. The pomegranate has strong branching power, so pruning extended branches in winter does not need to be cut short, only thinning out dense branches and underdeveloped secondary branches.

6. Reasonable fertilization In autumn, apply 100-200 kg of high-quality ring fertilizer and 1-2 kg of cake fertilizer to each plant; topdress urea once in June and August, and use 50-100 grams per plant for 1-2 years old trees each time, 3- For 4-year-old trees, use 200-250 grams per plant each time, and water as appropriate according to the rainfall after topdressing. Plastic film covering and tree tray covering 1-2 years old trees, covering plastic film once in early spring and late autumn;

7. In autumn, pomegranate trees tend to germinate many new shoots two or three times, which makes the canopy branches dense, resulting in poor ventilation and light transmission, slow fruit growth, poor coloring, and also affects the formation of flower buds on inner chamber leaf clusters and short branches. Therefore, it is particularly important to strengthen autumn pruning.

Branch Thinning: Continue to cut off dense, leggy, sprouting branches and sprouts with pests. It is required that the light spots under the canopy should be evenly distributed on the ground after branch thinning, and it is appropriate to account for 10%-15% of the projected area of the whole canopy. Ensure that the fruit is directly exposed to the light, so that the bushes and short branches of the inner chamber leaves are exposed to sufficient light, and the formation of flower buds is fast. Take deep burial or incineration of cut fruit branches with diseases and insect pests.

Density and topping: remove the elongated branches, upright branches, dense branches and slender branches in the inner chamber of the crown, and keep the interior of the crown ventilated and light-transmitting. Lightly pick the shoots that have not stopped growing but need to be retained for the purpose of cultivating the tree shape, so as to reduce nutrient consumption, make the branches grow full and strong, and ensure safe overwintering.

3. Management of wild leeks

Wild leek leaves, scapes and flowers are all eaten as vegetables; seeds, etc. can be used as medicine, which has the effects of nourishing the kidney, invigorating the stomach, refreshing, antiperspirant and astringent. Strong adaptability, cold and drought resistance, can be cultivated all over the country.
