How to achieve high quality and high yield cultivation of tomato cultivation? What kind of growth environment is suitable for tomato growth, and what are the better cultivation techniques? The analysis of tomato cultivation techniques is summarized as follows:
1 Tomato growth characteristics
First of all, the growth of tomatoes is inseparable from the sun. If the sun is not enough, it is easy to cause damage to the fruits or roots and leaves of the tomatoes. The result is that the flesh is small and sour, but the high light will make the plants Stop growing; secondly, the choice of ground soil for growing tomatoes is also important. It should be planted in a flat and open area, and the soil must have a certain fertility. The soil layer must have a certain thickness and is easy to irrigate. Then, the tomatoes are cultivated. The time is best chosen in December, which is most suitable for newly-developed seedlings. It also ensures that the time to mature the market occupies an earlier position. Finally, care is taken. During the whole process of tomato ripening, some plants should be trimmed. The local language is commonly called “branchingâ€, which can help the tomatoes grow in a healthy direction. In addition, if the plant grows taller and denser during its growth, it needs to be provided with a support. It grows healthily.
2 tomato cultivation techniques
2.1 Cultivation techniques
There are five technical aspects of this link that need to be addressed, namely, seed selection, pre-emergence, germination, and planting. And seedlings.
First of all, seed selection is a key link. For the topographic climate of Shanxi, drought resistance, strong disease resistance, high yield, and good quality seeds are the best choices, such as Dahong 1 and Beijing Pink Queen. There are also some hybrid varieties that are also excellent seeds.
Second, after selecting the seeds, it is necessary to carry out pre-cultivation and let them germinate, but a certain amount of preparation work must be done before germination, for example, disinfecting the seeds first, so that the seeds can be less or not affected by the bacteria during the growth process. Invasion, the specific means of disinfection is to soak in warm soup water, or replace it with trisodium phosphate. These two methods can ensure the seeds are smooth and safe to germinate.
Third, seed germination should be carried out at a suitable temperature, usually between 20 ° C and 25 ° C. In this environment, germination is required, and it is necessary to ensure sufficient humidity for the seeds. Watering should be carried out frequently, and real-time observation is required. , for tracking records.
Fourth, the tomato seeds after germination need to be planted, but before that, choose a suitable seedbed suitable for seed growth, and sprinkle the germinated seeds evenly on the selected seedbed. The seedbed must be watered beforehand. After the treatment, the soil is covered thereon, and after the seeds are sprinkled on the soil, if the influence of low temperature is concerned, the plastic film can be covered to maintain the temperature suitability, which can further ensure the seed emergence rate. Finally, the seedlings are divided. After the seedlings emit two leaves, the seedlings are divided into ten centimeters between each plant, and then covered with soil. The nutrients to be paid attention to during this period must be sufficient to ensure the seedlings. Survival chance.
2.2 Technical details during seedling growth
During the growth of seedlings, temperature is the most basic and most important attention detail. The temperature difference between day and night in Shanxi is relatively large. Therefore, it is necessary to ensure the temperature control of the seedlings every morning and evening to prevent seedling death due to cold and heat. In addition, it is also necessary to pay attention to the light, the seedlings need to be aerobic breathing, so ensure sufficient light. The planter should also pay attention to observe whether the soil moisture of the seedling growth is appropriate every day. If the water is insufficient, it should be watered in time and not too dry.
Seedling growth requires a lot of nutrients, just like a lactating baby, so don't give it nutrition.
2.3 Management techniques for plant growth period
The technical points of this period include slow seedlings, environment, defense against pests and diseases, fertilization and weeding, pollination, results, and period trimming. In the slow seedling period, if the vegetable farmer uses a greenhouse, it is necessary to ensure that it is closed for three to five days, which is beneficial to the smooth progress of the seedling. The growing temperature of tomato plants in the growing period should be controlled between 10 degrees Celsius and 15 degrees Celsius to ensure humidity and light. During this period, the breeding of pests and diseases is also serious. For those common, such as gray mold, root rot, aphids, etc., it is necessary to prevent them in advance, eliminate them with corresponding insecticides, and regularly fertilize tomato plants. The wild weeds should be removed in time, because these wild weeds around the tomatoes will absorb the original nutrients of the tomatoes, making them slower, the roots and leaves of the plants become smaller, and even breed pests and diseases, so timely Clean up. Tomato pollination is indispensable, and artificial pollination is used in some cases, including some farmers who release their own bees to help the tomatoes complete this important step, so as to effectively ensure the growth environment and quality of the pulp. Nutritional ingredients are not lost. Finally, it is the trimming process. This technique is also very important. The principle of pruning is that each tomato can leave only three or four spikes, otherwise too much will make each tomato have insufficient nutrients, and The taste is not good, there is a sour feeling.
Tomatoes are varieties of vegetables with high nutritional value. Its market demand also determines that its planting area will be larger and larger. In order to adapt to this large market supply, it is necessary to produce high quality nutrient-rich tomatoes. Therefore, cultivation techniques are particularly important. As can be seen from the narrative of this article, the cultivation techniques of tomatoes require extremely careful learning and attention, so as to ensure their quality and yield.
Black tea (dark tea) is named after the black appearance of the finished tea. It is one of the six major tea groups and is a post-fermented tea. The main production areas are Guangxi, Sichuan, Yunnan, Hubei, Hunan, Shaanxi and Anhui. The traditional black tea is made from high maturity black wool tea, which is the main raw material for pressing tightly pressed tea.
The process of making black tea generally includes four steps: killing, kneading, stacking and drying. Black tea is mainly classified as Hunan black tea (Fu tea, Qianliang tea, black brick tea, Tri-tip, etc.), Hubei green brick tea, Sichuan Tibetan tea (border tea), Anhui Gu Yi black tea (An tea), Yunnan black tea (Pu'er tea), Guangxi Liubao tea and Shaanxi black tea (Fu tea) according to geographical distribution.
The yellow powder in black tea is commonly known as golden flower, a beneficial microorganism, the so-called golden flower, is in the processing of raw materials through the flowering of this special procedure, specifically in the black tea bricks to cultivate a kind of coronary aspergillus substance called coronary scattered cystic bacteria, commonly known as the golden flower, observed under the microscope, each individual golden flower is umbrella-shaped clusters, the whole body is golden and eye-catching, ringed into a group, evenly distributed.
