I. Varieties and characteristics
Israel's large fruit-type tomatoes, suitable for solar greenhouses, are mainly excellent varieties such as gathea and hito. It is a warmer vegetable, with late-cooked varieties, with unlimited growth of up to 10 months, and a well-equipped greenhouse for more than 20 months. More than 10 metres high, which is usually harvested 70 to 80 days after planting, with thick skins, strong storage, good taste, colour, resistance, low temperature and resistance to various diseases, is one of the good seeds for the development of a scalable and marketable vegetable production。
Ii. Cultivation measures
Cultivation
In mid-august, seedlings were grown in the open, preferably with nutrition. (c) nutritional homemade: 6 per cent of fertile field soil is fertilized with rotting cortex, 4 per cent after sifting, 50 per cent more fungus or 50 grams per cubic metre of trophic soil, then laid in a seedbed, 12 cm thick. Zirconium is 1. 2 to 1. 5 metres wide, with an unlimited length. The pre-plant seedbed is soaked that it can be soaked when it seeps. The seed is soaked for six hours before seeding, after which it is ploughed with fine sand, then seeded around 100 grains per square metre, and the seed is scattered three times to ensure that the seed is evenly distributed (one seed per seed per trophic seed). Upon completion of the programme, the soil is scattered at 0. 5 to 1 cm and the membrane is then covered. When most of the seed's topsoil is removed, water is often sprayed, the seedbed is kept wet and the spraying takes place in the evening. It's supposed to be planted in the solar greenhouse when it's 7-8。
2. Plantation
(1) cleans up the whole area of the pre-harvest crop with the application of fertilizers, combining the tillage with the application of 4000-5,000 kg of fertilized organic fat or 3,000 kg of chicken dung per acre, and smoothing the dredges; then apply the diammonium phosphate and 30 kg of potassium sulphate per acre with the application of the gutters at a distance of 90 cm, 60 cm and 15-20 cm deep. It is 90 cm wide, 60 cm small and 20 cm high. The solar greenhouse with a single-dip system with two rows of drip irrigation can fill a gutter with a drip hose。
(2) once after the sterilisation of the shed, completely disinfected. High-temperature suffocation can be used, with a closed membrane, 4 to 5 days of sterilisation in the middle of the sun, and 100 times more liquid spray can be disinfected by the ff。
(3) watering of seedbeds prior to seedling planting for the benefit of seedlings. The seedlings are grown with as much soil as possible, with two rows per plant, 40 centimetres away, and sufficient water for planting. The day after the planting may be served with fresh water, and the land shall be dried with pine soil. The membrane will be covered in a timely manner. The temperature of the shed is not more than 30 degrees. When the seedlings are slow, the first fruit does not normally water and fattens, and the first fruit sits and then waters once. Combining the water with nitrogen, phosphorus, potassium compound fat 15 kg per acre. Fertilizers may be dissolved in the reservoir by drip irrigation equipment and applied with drip irrigation pipes。
3. Post-plant management
(1) a single whole sapling is timely to the length of 30 to 40 cm. When the first sap grows, it's almost possible to remove all the @-t from the lower part. The first is about four, the second is between five and eight, on average, and the next is about five。
(2) temperature light management winter management focuses on keeping temperature up to 28°c left during the day
Right, 10-15°c at night, while maintaining sufficient light, the grass must be emptied in a timely manner, and an additional general sheet of film can be built on the grass, so as to protect the temperature, the rain and snow, and the large sheet of film from dust and grass in a timely manner so as to maintain light。
(3) the management of winter and spring fertilizing water during winter - as little water as possible to prevent the temperature from falling faster. It is advisable to store relatively mild water in greenhouses for a period of time, with 15 kg of compound a fertilizer per acre being applied to water. By the end of february and the beginning of march, temperatures were gradually rising, allowing for a gradual increase in the application of fertilizers, an increase in the number of water draughts, one water draught every 7 to 10 days after march and a combination of fertilizers, as well as external fatting with active potassium on the leaves, while enhancing ventilation. When the plant grows to the top of the shed, the chicken falls. The way to do this is to hang one or two of them on another rope, cross-change them, and lift the front film of the greenhouse later in april to prevent too high temperatures。
4. Disease control is more resistant to the disease in garcía and the popular tomatoes. The main diseases are leafy and greyy diseases, which can be prevented by reducing greenhouse humidity through improved ventilation management. In the early stages of the disease, the leaves are removed in a timely manner, the fruit of the disease is removed and the treatment is done using 75 per cent of the bacteria to clear 600 times the humid powder or 50 per cent of the humid powder at the speed of 2,000 times the liquid spray。
