I. Variety selection The use of cherry tomatoes, Qianhong 1 and Japanese golden beans have a strong growth potential and a long period of results. The middle and late-maturing varieties are elevated. It is cultivated in ridges with a width of 1m and a narrow row of 0.6m, and is planted at about 3,000 per 667m2.
Second, the pruning technique When the trunk junction 2 fruit, leaving two leaves at the top topping, the fruit branch is called the first result of the branch. When the fruit of the first inflorescence begins to be harvested and the fruit of the second inflorescence begins to swell, a strong lateral branch below the top of the ear remains, instead of the trunk continuing to grow. According to the growing condition of the plant, the second branch of the fruit on the side branch grows again and this is the second result branch. When the fruit of the second result branch begins to be harvested, a strong lateral branch is again selected as the third result branch from the upper part, and so on. During the whole growth period, the toppings were exchanged for 6-7 times, and 6-7 branches were retained per plant, leaving 12-14 ear fruit.
After the branch is left in good condition, all the other side branches will be wiped off, and the collaterals should not be destroyed prematurely. Generally, when the length is longer than 20cm, 2 leaves will be destroyed. This will make better use of side branches to promote tomato growth.
Third, the falling vines are controlled before the vines are sprayed to reduce the water content in the vines and enhance their toughness. Falling vines should be carried out in the afternoon on sunny days. At this time, the stalks have low water content, soft tissue, and easy operation, avoiding and reducing the damage stems when falling. When falling, the old yellow leaves and diseased leaves in the lower part of the vine should be removed and taken outside the shed and buried deep or burned. The fruit in this area should also be harvested to avoid the onset of leaf and fruit on the wet ground after falling, forming the onset center. When the first inflorescence is open, hang it. After the fruit of the first fruit branch is harvested, the first fruit of the second fruit branch rapidly enlarges, and the second fruit is caught while the first fruit is caught. After that, each result must be harvested once after harvesting.
Take the method of cross-sweeping between plants and plants, that is, remove the plants from the ropes, knock down the old leaves, and gently twist the plants to the same nearby plants and then hang them again. The falling vines must be in the same direction in an orderly manner and gradually coiled around the cultivating ridges. When winding the stem, it is necessary to bend the vine with the natural curvature of the stem. Do not forcibly bend or reversely bend, avoid cracking or breaking the stem. Each vine maintains leaf vines 15 cm from the ridge surface. Each plant maintains more than 20 functional leaves. The plant height is maintained at 0.8m (shenan) to 1.5m (shebei) from the shed. Pay attention to the front row of plants. The top of the stem should not exceed the back row to avoid shading. Ensure that the leaves are evenly distributed, always in the best position for the three-dimensional lighting and the best state of the leaf area, and keep the leaf area coefficient at 3-4. The whole growing period falls 5-6 times.
IV. Management after pruning
1. In the days after the pruning occurs, the temperature in the shed must be properly increased to promote wound healing. The daytime temperature should be maintained at 20-25°C and 15°C at night.
2. In order to prevent the invasion of germs from stem vines and leaves wounds, according to the regular incidence of cherry tomatoes, after the pruning vines sprayed after the fasting spirit, gray mold grams, chlorothalonil, mancozeb and other agents control Leaf mould, gray mold and early and late blight. When spraying pesticides can be added when the rain 101 leaf fertilizer, can prevent disease, but also increase production.
3. Fallen vines of fertilizer and water management can reduce the result position of the plant, but it cannot shorten the actual distance between the result site and the root system. Coupled with the growing body of nutrients, such as insufficient supply of fertilizer, will cause the quality of the result is getting worse, the fruit is getting smaller and other issues, therefore, should provide sufficient fertilizer and water to meet plant growth needs. The top dressing is mainly potassium sulfate such as potassium sulfate, and the top dressing is 15-20 kg per 667m2, and watering is performed at the same time.
4. Snoring and picking the old leaves After the fruit on the branches is picked, the side branches below the branches are to be promptly knocked out to ensure nutrient supply to the fruit set branches, and all the leaves under the result branches are removed. The leaves on the ear cannot be removed to ensure that the upper layer of fruit develops well. Snoring and picking old leaves are done on a sunny day to facilitate wound healing. When you snoring, your hand only touches the lice and does not touch the stem to avoid spreading the tobacco mosaic virus. The leaves should be removed as close to the branches as possible, and care should be taken not to leave the stems to prevent gray mold.
Second, the pruning technique When the trunk junction 2 fruit, leaving two leaves at the top topping, the fruit branch is called the first result of the branch. When the fruit of the first inflorescence begins to be harvested and the fruit of the second inflorescence begins to swell, a strong lateral branch below the top of the ear remains, instead of the trunk continuing to grow. According to the growing condition of the plant, the second branch of the fruit on the side branch grows again and this is the second result branch. When the fruit of the second result branch begins to be harvested, a strong lateral branch is again selected as the third result branch from the upper part, and so on. During the whole growth period, the toppings were exchanged for 6-7 times, and 6-7 branches were retained per plant, leaving 12-14 ear fruit.
