1. Rational selection of varieties and scientific construction of japanese tomatoes is less demanding for soil, but best in sandy border soil with ph values of 5. 5 to 7. 5. The average annual temperature above 13°c is appropriate, and the temperature is too low for the development of tomatoes. It would be preferable for the construction of the park to be preceded by the conversion of trenches or the planting of large caves. Most japanese tomato varieties are female, but they are monolithic and more productive if they are planted to pollinate. It was therefore important to make reasonable choices about the main plant varieties. Markets must be selected for marketable, large, beautiful, fruit and meat lax, with no or little seeds, and high-quality, full tomatoes of good taste, with medium- and late-literated varieties of jiro, yingjin, zing 20 and wealth-based. In order to increase the variety of coloured varieties and increase sit-in rates, the pre-maturized early birth of matsumoto and the early birth of west village can be grown in appropriate quantities. The pollinating tree is best equipped with a zenji pill, with a ratio of 8 :1. Tree planting is possible from october to march of each year. Plantation density is appropriate for 111 acres (3 m x 2 m). When planted, the roots are filled with water and the trees are covered with weeds. (i) fertilizing: 1. Fertilizing in early orchards (one to two years after the planting of a dense garden): the fertilisation of young trees is based on nitrogen fertilizer, combined with phosphorus and potassium, and is done in an industrious manner. The first fertilisation in a year after the spring sprouts of a plant garden was established, with 5-10 grams of urea and 5 kg of human and animal dung, followed by one to two per month thereafter, with an appropriate increase in fertilizer use and fertilisation with phosphorus, a loss of fertilisation (to promote flowers) at the end of july, and the application of urea in mid-september. One fertilization in march, may, august and late september of the following year, with the exception of the late september organic fertilizer, which was dominated by organic fertilizer, the rest by quick-impact nitrogen and phosphorus. 2. Fertilization in adult orchards (after the third year of dense plantations): the high production of japanese tomatoes makes it more fertilized. In general, a total of 0. 84 kg of pure nitrogen, 0. 94 kg of pure phosphorus and 0. 94 kg of pure potassium are applied to each 100 kg of fruit production, with three fertilization times per year. Fertilizing before the first sprouts in mid-march improves the quality of the flowers while at the same time allowing them to grow in the spring and lay the foundation for production in the coming year. The average acre is 15-20 kg urea and 1,500 kg organic fat. The second fertilisation was applied in early july, 55% - 60% of the year. This is the period of fruit expansion and physiology of buds, and nitrogen and potassium fertilizer should be re-applied to promote gravitation, while at the same time contributing to fruit expansion. Normal acre urea application of 35 to 40 kg, potassium sulphate of 30 kg, calcium perphosphate of 20 kg and organic fat of 3,000 to 4,000 kg. The third application, which was based on organic and phosphorous fertilizers at the end of october, provided an adequate source of nutrients for the next year's abundance, accounting for about 25 per cent of the annual fertilization, 4000 kg of organic fertilization and 50 kg of calcium perphosphate. 3. Leaf fertilization: leaf fertilization is combined with spraying of pesticides, typically with 0. 2% urea, 0. 1% ~0. 2% potassium dihydrohydrophosphate and 0. 1% trace elements. (ii) soil management: japanese tomatoes are highly wet, drought-resistant and poor-growing. The branches are the best growing when the soil is 30 to 40 per cent water. Therefore, it is necessary to cultivate deep, use more organic fertilizers and pay attention to weeding, weeding, irrigation, etc. Iii. Increased sit-in rate and prevention of artificial pollination of physiological fallout 1. Through pollination, the jiro and rich are able to increase sit-in rates and prevent physiological fallout. Its pollinators are scheduled to be yellow and white in petals and pre-open bellies. The flowers will be dried, pollen sifted out, filled with brown bottles and stored in the freezer room. To save pollen, defaminating powder, starch powder, chestnut pollen, etc., can be used as an incremental agent, diluting the pollen 30 to 50 times, and giving it one to two times a quil point within three to four days of flowering. 2. Timely flowering and fruit-cutting. The determination of a reasonable load through grafting and charisma can reduce nutrient consumption in the tree, raise the amounts of tomatoes left behind, and encourage the gravitation of flowers to ensure production in the following year. The flowering begins with the opening of the first flower on the branch of the result and the closing of the second flower. One or two flowers are kept from the base to the second and third, and the rest are removed. Succeeding is mainly deforming and insecticidal. As a result, there were no results for the branches under five leaves, 1 for the 6-10 leaves and 2 for the more than 11 leaves. 3. The introduction of such measures as flower bee-laying and cycling have also played a significant role in increasing sit-in rates and reducing the biological fallout. Iv. Integrative trim (i) wholestyping: the condensed sweetener complex is dominated by a small coronal evacuation layer. Naturally happy shapes can also be used for density of 3 m x 2 m or 2 m x 1. 5 m. (ii) cutting 1. Long-term trimping: in april-august, long-term trimping was carried out using techniques such as sprouts, twists, heart breaks, etc., to select the right main side branches, the resulting branches, and the adjustment of the branches, so as to fully conserve nutrients and promote early flowering, early formation, production and production. 2. Intersleep trim: primarily to cultivate tree structure, maintain the whole tree shape, control tree heights and canopy, give fresh air to the tree, and remove all of the old, weak, sick and dead branches. The long branches are either cut out or pulled or cut short, depending on the circumstances. It is advisable to keep the result branches in the same size, length and even distribution within the tree canopy. It is updated on a rotational basis, in due course, to maintain a robust capacity for results. The branches extending between the strains and the rows should be duly retrenched at a later stage so that there is no excessive cross-section between the strains and a 50 cm corridor between the rows. V. Pest and pest management 1. Rationally trimmed luminum so that trees can be ventilated and the humidity of orchards can be reduced. In winter and spring, the disease is cut to remove the residual source of the disease from the tree to reduce the source of initial leaching. The disease can be prevented by a 5-degree thiomer sulphate spray before the sprout occurs, followed by a 0. 3-0. 5-degree thiomer or 1 05-400 poldolum. In may-july, 70 per cent of methyl tobuzini was sprayed 500 times, 40 per cent of dubunfort was 4,000 times or more than 50 per cent coarse 1,500 times, and 70 per cent of dyson manganese zinc 500 to 800 times. Tomatomy control: in the early stages of winter insect plume (early may), after weed removal, 4% of the ecstasy octopus per tree is sprayed under the tree canopy, 0. 2 - 0. 7 kg, and again 10 days later, to poison the larvae. In the early stages of the larvae (june), 20 per cent of the pyrethroid milk was sprayed from 2000 to 3000 times, and 40 per cent of the rheumate cream from 800 to 1,000 times, every 10 to 15 days, to poison the larvae. Aphids: mainly platinum, grass-crazy, japanese turtle wax, etc. The response was mainly to spray 40 per cent of the larvae concentrate 800 to 1,000 times more liquid, with better results. In addition, the effect of the 40 per cent fast-stamping of 1,000-fold liquid control was also evident. After harvest, manage the yield period between harvest and fall, which can provide for the seeding and flowering of the following year. Farmers are now leaving orchards under management once they are harvested, making it impossible for the tomatoes to accumulate sufficient nutrients and even to fall early, leading to lower and unstable yields. Post-harvest foliage management and pest control should be strengthened, with timely fertilization and watering and, where necessary, leaf-face fertilization, in order to maintain the health and vitality of the leaves。
