Ornamental cherry tomatoes autumn pot technology

In recent years, with the popularity of ornamental vegetables, the ornamental value of cherry tomatoes has become more and more important. It can be used for landscaping of parks and green lands, and it can also be used as a home for potted landscaping. It has broad application prospects and large-scale cultivation, and can also obtain considerable economic benefits. The cultivation techniques are as follows. 1. Select a suitable variety of ornamental cherry tomatoes, you must select special varieties. No matter whether the fresh food grows in a limited way or grows indefinitely, it is not suitable for ornamental plants because the plants are tall. The "Jinyu" and "Red Jade" varieties of the "Jinyu" and "Red Jade" varieties selected by the Vegetable Institute of the Zhejiang Academy of Agricultural Sciences are special for cultivating potted plants. The plants are short and strong, their plant types are compact, the results are concentrated and precocious, fruit shape is good, fruiting time is long, fruit Colorful, "red jade" is red, "gold and jade" is golden yellow. 2. Seedlings and Seedlings The lower reaches of the Yangtze River can be planted for many seasons in a year. Autumn cultivation should be planted in the early to mid-July and can be listed during the National Day. Loose soil or peat, ash, vermiculite, etc. can be used as seedling substrate for sowing. Seeds should be disinfected before sowing, evenly sowed, covered with soil or substrate, irrigated with water, covered with opaque plastic film or straw kept moist, placed in a greenhouse or shed. 2-3 days to emerge, control the temperature after emergence, determine the amount of water according to the weather and the substrate, and keep the air and light. When about 2-3 true leaves are grown for about 15 days, they are planted directly in pots with a diameter of 15-20 cm. 3. Colonization management 1 pot soil preparation can be used for three years did not plant the loose garden soil of eggplant vegetables. In order to prevent the occurrence of infectious diseases in the soil, cultivation of substrates can be used. Commonly used substrates for potted plants include vermiculite, peat, sawdust, arbor, ash, and perlite. Specific preparation can be equal volume of wood chips and wet pig manure mixed and fermented for 30 days, and then matched with the same volume of ash mix (three ratio of 1:1:2), can be loaded into plastic basin in. 2 Before the discharge of potted pots, the plastic pots can be laid on the floor of the pot before discharging, and then the pots can be drained to prevent the tomato roots from drilling into the soil from the basin drain holes. The pot roots cause the plants to wilted when they move. death. To facilitate early growth management, pots can be drained tightly. When the plants grow to a certain size and squeeze each other, the spacing between the pots and pans should be increased accordingly, and the plants can be arranged 2-3 times in the growth cycle. In order to avoid excessive plant density, resulting in plant growth, the base stalk elongated and thinning, resulting in top-heavy, plant can not stand upright, and affect the ornamental. 3 Fertilizer water management Planting the plant growth in front of the plant, the plant growth is slow, when the leaf color fades, cast thin human fecal urine 1-2 times. When the leaf color is yellow, 0.5 g of urine can be applied to each pot or a 0.2% urea solution is sprayed on the foliar surface to ensure that the plants grow well. After fruit set, apply urea solution to topdressing once. Watering can not be excessive, otherwise it will cause disease due to high humidity. In case of continuous high temperature and drought, water should be poured every morning, and the rainy days will depend on the degree of matrix wet and dry, and the matrix will not be dry without watering. 4 After the temperature control was planted in August, the area south of the Yangtze River in China is in a hot season. It is very important to do a good job of cooling. The shade net is covered before 9 o'clock in the morning and the net is collected before 4 o'clock in the afternoon, which can reduce the temperature in the greenhouse and ensure the illumination of the plants. Rainy days can not cover the shade net. In case of continuous sunny high temperature, it can be properly sprinkled to cool down. At the same time, ventilation and ventilation in the shed should be maintained, which can reduce the temperature and prevent the occurrence of pests and diseases. 5 Use of growth regulators In the middle and late August, potted tomatoes gradually bloomed. High temperature during flowering may affect fruit setting. When there are 2-3 flowers in each spike, spray with 25mg/L liquid. Use a hand-held small sprayer to align the spray of flowers to avoid spraying the spray onto the leaves and to prevent injury. 6 Pests and Diseases Tomatoes cultivated in the medium as long as the discharge density is appropriate, the temperature and humidity are well regulated, and the general diseases are less. Insect pests mainly include locusts and tobacco insects. Occurrence of H. assults can be manually captured. Severe occurrence can spray 90% trichlorfon crystals or 2.5% Kung Fu EC 5000 times spray. Aphid can be used 50% to avoid fogging WP 2000-3000 times, or 25% chrysodetone 3000 times control. 4. The structure of pruning and pruning matrices is loose, and it is easy to cause the plants to dump when handling. Before the shed, proper amount of soil is cultivated at the base of each tomato to help the roots of the plants to be stable. Some old leaves, wormholes, and some excessive leaves are removed so that most of the fruits of the tomatoes can be exposed outside the leaves to produce fruitful results. Too many plants in fruiting must remove some of the fruit and cut off the side branches that affect the plant shape, making the plant type more compact and more ornamental.

Bleach Clean-up Enzyme is developed to remove residual hydrogen peroxide.Usually the cotton fabric bleached with hydrogen peroxide, the bleaching chemicals must be removed before dyeing in order to avoid the reaction between the bleaching agent and the dye. The traditional way to remove bleach is to rinse the fabric several times with water. Alternatively, you can use a mild reducing agent to clean the bleach. In addition, a large amount of water is needed in rinsing which wash out a large amount of wastewater.

Conzyme CAT200 is an extremely high concentrated liquid catalase preparation. It is specially developed to remove residual hydrogen peroxide and improve the last preparation prior to dyeing; it can largely reduce hazardous chemicals usage and save water.

Benefits:

Complete removal of residual H2O2 in preparation for dyeing
Wide pH range, convenient in using
No damage of fabric
Reduce processing time
Reduce water consumption and effluent volume

Environmental-friendly & bio-degradation


Enzyme preparations belong to protein, which may induce sensitization and cause anaphylaxis in sensitized individuals. Long-term exposure may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
