Young crops intercropping techniques for apple orchard

Young apple orchard intercropping watermelon

1. Fine selection: In the planting, market positioning should be done as early as possible, and the varieties should be carefully selected so as to be marketable.

2. Reasonable selection: Watermelon does not require strict requirements on the previous crop, but watermelons planted on different crops have a greater impact on yield and quality.苜蓿茬 is the ideal front hoe, and the better 茬 is bean, wheat, corn, artichoke and so on.

3. Deep-sweeping soil: The watermelon root system is strong and well-developed. It has a short growing time and a large amount of growth. It concentrates the consumption of nutrients in the soil and consumes a large amount. During the production, the soil should be deeply turned in order to create a loose soil structure and promote roots to lower the level. The formation of a strong root group, increase the absorption capacity of watermelon, the general depth should be more than 30 cm.

4. Apply base fertilizer: Apply enough base fertilizer before planting watermelon. Apply organic fertilizer, phosphorus and potassium fertilizer, and 70% of nitrogen fertilizer should be applied one time before sowing. Apply organic fertilizer per acre should be between 5000 and 6,000 kg. Superphosphate 150 Kg, potassium sulfate 100 kg, urea 30 kg or more, in order to form a fertile soil structure, protect the watermelon growth material supply, in order to facilitate the increase of watermelon production.

5. Appropriate sowing: Watermelon planting will directly affect the planting efficiency of watermelon in the morning and evening. It will be covered with small sheds and plastic mulch. The cultivated watermelon will be cultivated in the morning for 7 to 10 days. The ditch will cover the watermelon in the week before Qingming. Sowing is more appropriate.

6. Appropriate and sparse planting: In the management of watermelon, the most important feature is that the plants are allowed to grow and leave more vines. This determines the planting density should not be too large. Generally, about 700 plants per acre are suitable, and the planting is too dense. Competitive nutrition affects growth and adversely affects yield, quality and efficiency.

7. Shun Mangman: When watermelons are planted, more vines are left, but it is never a matter of twigs. It is the simplification of management procedures. It is no longer carried out by vines. During the growth of the watermelon vines, the vines are swayed in one direction, and then the vines are fixed with short wooden sticks to prevent the wind from blowing and running over the fields.

8. Moderate seat melon: Watermelon seat melon is very particular about: the first female flower due to the plant leaves less, the seat melon is limited due to nutrient supply, it is difficult to grow up. Since the flowering of each inflorescence differs by 5 to 7 days, and after the third female flower, the mature period is postponed, the selling price of watermelons declines, and the production efficiency is unfavorable. Therefore, the most suitable place for watermelon is the second female flower, which is the best place for watermelon production. Through the implementation of artificially assisted pollination and melon field-inducing bees and other measures, the second female flowering melon should be guaranteed and the production efficiency should be improved.

9. Dressing and watering: The watermelon grows for a short period of time, has a large amount of growth, and consumes much fertilizer and water. In the production, fertilizer should be supplemented in a timely manner to ensure the growth of the plants and promote the plants to grow robustly so as to increase the yield. When the critical period of watermelon water requirement is the size of watermelon walnut, the vegetative growth and reproductive growth of the plant will enter the period of rapid growth. It is necessary to timely top-dress water and ensure the supply of nutrient water. During this period, topdressing should be based on fast-acting nitrogen fertilizers, supplemented with foliar spray fertilizer, and full nutrition supplements. The top-dressing top dressing should be dominated by ammonium bicarbonate. The foliar spray fertilizer should be based on potassium dihydrogen phosphate, and ammonium bicarbonate should be the best combination. Water irrigation facilities. Watering can be flexibly controlled according to soil moisture and weather conditions. There are no watering conditions in the mountainous areas, and irrigation of large areas with agricultural tricycles is used to pull water for irrigation. This creates conditions for the pouring of fertilizers.

10. Pest control: The main pests in watermelon production are blight and aphids. The key to prevention and control is to control the hazards before and after the wheat harvest, spraying once again with anti-dry spirit + scorpion net or imidacloprid, dipyridamole.

Young apple orchard interplanting pepper

1. Plow the soil in the orchard before pepper sowing: Since the pepper is a high-yielding crop, the cultivation density is high, and the soil is not easy to manage after planting. Therefore, the soil should be ploughed once more, with a depth of 35 to 40 cm.

2. Applying Fertilizer: Pepper is a crop that requires more fertilizer. Fertilizer should be applied before sowing so as to ensure the improvement of pepper production. Per acre should be applied more than 6,000 kg of soil miscellaneous fertilizer, with a total of 1,000 kg of plant ash, 50 kg of superphosphate, 15 kg of urea; in the early stages of flowering, raining 10 kg of urea per mu or spraying urea, watering to meet The nutrients required for rapid growth of peppers.

3. Cover cultivation: Immediately after sowing pepper, cover a layer of 3 to 5 centimeters of fine cotton, which will not only protect the cockroach and increase the temperature, but also increase the temperature difference between day and night during the growing season, increase the proportion of red pepper, increase the commercial quality, and cover the sand. Sand and soil are required to have uniform thickness.

4. Reasonable Leakage: When the pepper has 3 to 5 true leaves when the thinning. The peppers are suitable for clustering, and 2 to 3 plants can be kept in each cluster. The cluster spacing is 4333 cm (two plants per hole or 6626 cm (3 plants per hole) are appropriate.

5. Moisture management: Shallow watering once in the initial flowering period of pepper, and keeping the field water holding capacity between 65 and 70% before flowering ends. As a result, field capacity should be maintained at 80 to 90%.

6. Fruit tree management: Water and fertilizer pest management is the same as watermelon. Soil management should be conducted in time after the pepper harvest, deep plowing expansion points, micro-areas to improve soil, optimizing the root growth of the environmental conditions, to create a good root growth and environmental conditions in order to achieve strong roots and promote fruit tree growth.

Young apple orchard interplanting broad bean

1. Choosing good varieties: When interplanting with young apple orchards, it is necessary to choose varieties with large grains, big pods, low initial pods, good pod habits, and stable yield, so as to facilitate high yield and stable yield.

2. Fine soil preparation before planting: 3000 kilograms of high-quality farmyard fertilizer and 25 kilograms of compound fertilizer per acre shall be applied before sowing, and the fertilizer shall be evenly spread on the surface, and then rotted with a rotary cultivator to create important conditions for loose soil.

3. Appropriate sowing: Broad bean sowing before and after the Qingming, sowing by spacing 1 meter, spacing 35 cm standard on-demand, sowing depth of 5 to 8 cm.

4. Seedling management: In order to promote growth, in the seedling stage, timely eradication of weeds, reduce the consumption of nutrients and water in the weeds, 7.5 kg of urea per acre before rain, to promote seedling growth, flowering plants The increased demand for nutrients can be combined with weeding to conduct a top-dressing fertilizer, with about 10 kilograms of urea per mu.

5. Anti-mites: Aphids are the main insect pests in broad bean production. They can be combined with fruit trees to prevent pests and insects, spray insecticides, etc. to control.

6. Harvest: Harvest should be done when the grain is full and fully matured and the pods shrink.
