First, the selection of varieties Spring, autumn and winter are optional Golden Diamond 1 (with Barrier 1114), Gold Apple 424 Hon Hai 2301, Chunhui II, Xia Hui 2, Qiu Hui 438, Jin Hui 458, Jin Hui 468, etc. Strong growth, no premature aging, extremely high yield, and excellent quality (Jinhui 458, Jinhui 468 are generally only used for spring and autumn planting). In mountainous areas with an altitude of 300 meters above sea level, they can also be planted in March-June for anti-season cultivation. In summer (except June high temperature period), Xia Hui, Chunhui, Xia Sheng No. 1, Xia Sheng No. 2, and Jin Hui 458 shall be selected. New summer and other varieties that are resistant to light, high temperature, moisture, and high resistance to bacterial wilt.
As Golden Diamond 1114 and Golden Apple 424 are relatively strict on the planting environment and technology, the following only describes the technology of other varieties, and the cultivation techniques of Golden Diamond One and Golden Apple, please refer to other materials.
Second, nurture strong seedlings
1, bed soil preparation and disinfection will be fully cooked farmyard fertilizer and onion, garlic garden soil mixed by 4:6 ratio of sieving, formulated as seedbed soil, with each additional cubic meter after infiltration of 250 grams of urea and 1- 2 kg of superphosphate, plus 50 grams of carbendazim (or mancozeb) and 100 grams of phoxim in every 50 kg of bed soil, can be activated to kill bacteria and insects. Spray water with a sprayer so that the water content reaches the size of the hand. The degree of landing and scattered, and then into the nutrition cup.
2, soaking seed disinfection, germination tomato seeds into warm water of 55 degrees Celsius, stirring constantly to 25 °C, soaking for 10 minutes to remove, put in 1% potassium permanganate solution soak for 15 minutes, with a gauze pocket filter, tie A good bag mouth, into the water and wash until the water becomes clear, then soaked in water at 25 °C for 4 hours, remove and drain, germination to dew, ready to broadcast.
3, sowing with a small bamboo stick to loosen the soil in the middle of the nutrition cup, and then each of the nutrition cup central seed priming seeds 1-2 capsules, cover about 1 cm in nutrient soil thickness, and then the nutrition cup neatly discharged in the width of 12 cm, depth 16 On a low centimeter, the length may vary, depending on the situation, then covers the mulch and places a small bow awning on both sides. In winter and spring, the tomato is planted and the tomato is covered with plastic film and bitterness in early spring; the summer plant and autumn and winter are covered with sunshade. Plastic film, in the 1 leaf 1 heart, and time seedlings to ensure that each nutrient cup has a seedling.
4. Management of seedling stage Winter and spring planting seedlings Pay attention to prolong the light, strengthen insulation, ventilate and ventilate moisture, regulate light, temperature, and humidity in the nursery protection facilities, and master the damping-off disease and blight. In early spring, tomato should be strengthened with heat preservation, ventilation and humidity, and extended lighting. Pay attention to avoiding rain and avoiding strong light in the later period. Prevent main diseases such as early and late blight and virus disease: Shading and sheltering should be paid attention to in summer and summer. Cooling, dwarfing control, etc. can significantly reduce virus invasion and cultivate healthy seedlings.
Third, intensive cultivation, reuse of basal fat - generally per 667 square meters of cooked chicken manure or cow dung (add 10% phoxim 812 powder per 50 kilograms of fertilizer or 10% grain granules 200 g mix, buckle film 7 days) 5000 kg for 50 kg of fertilizer and 50 kg for Norwegian compound fertilizer or 20 kg of superphosphate. Land must be "three ploughs and three rakes" to achieve the objective of crushed soil and sulphur-relaxation to lay the foundation for stabilizing production.
IV. Prevention of seedling diseases during planting For every 50 kg of fixed-root water, 30% of the mycobacterial enemy 60 grams or 72.2% of kelipek 50 grams can be added to prevent seedling disease. Line spacing 60 cm x 40 cm. About 3,200 plants per 667 square meters of Jinling No. 1 per acre planted 1800-2000 strains were planted on a cloudy day afternoon and the roots were set. Be careful not to plant after heavy rain.
Fifth, the field of water and fertilizer management attention to the former control in the promotion after the attack and colonization to the slender seedlings, appropriate loose soil, pay attention not to dry, can be used 0.2% of urea and 0.2% potassium dihydrogen phosphate mixture for foliage fertilizer promotion Slow early seedlings. Slow seedlings to the first inflorescence fruit enlargement. Chasing 1-2 times of diluted feces to raise seedlings, take a good breeding stand; first-ear fruit to 4th ear fruit just blooming as a fruit period, pay attention to heavy fertilizer (mainly nitrogen and potassium fertilizer), re-swollen Water, catching 8-10 kilograms of urea and potassium sulphate per mu every 10 days. The fruit of the first ear was whitened to the garden, watered once every 7 days, and a mixture of 0.2% urea and 0.3% potassium dihydrogen sulfate was sprayed on the leaves to promote rapid fruit enlargement, prevent premature decline, and increase yield. .
Sixth, timely sparse fruit thinning, to promote the fruit of the tomato when the plant height of about 33 cm when the plant should be timely bamboo, tied vines, while removing lateral buds, pruning generally the first order of the following leaves removed, retaining the middle and top leaves In order to cover fruit and prevent mouth burns. There are several kinds of pruning: single dry pruning, pruning dry half pruning, double dry pruning, pruning can be determined according to the planting density using 3 different methods, one or two of them can also be used.
Early-maturing and self-sealing tomato varieties—like fruit set, fruit size is too small, it is necessary to carry out sparse flowering and fruit thinning during full bloom or full fruit period. The number of controlled fruit per plant is about 40. When the fruit of each ear is large, for example, broad beans, leave 3- 4 good fruits, dredged excess flowers and fruits and deformed fruit. In order to concentrate the supply of nutrients, in order to increase the weight of the single, increase the level of commodity. Note: Please select sunny for pruning and thinning and fruit thinning. Due to the low temperature in spring and winter and the falling of fruit in high temperature in the fall, the state must use 2.4-D within 3 days of the flowering of the tomato (When the temperature is higher than 15°C, the concentration is 10mg/L. When the temperature is lower than 15°C, the concentration For 20mg/L) silk flowers, each flower can only be processed once.
Seven, the fruit red red general winter and spring planting results in the early and autumn and winter planting results in the middle and late to 30% of the available ethephon 2000 15mg/L smeared ripe fruit fruit surface or plucked fruit in 2500mg/L solution soak 1-2 Minutes, when the fruits are stacked in a hotbed at 22-25°C, the fruit can be red-marketed after 4-5 treatments.
VIII. Pest Control Bacterial wilt: A bacterial disease. In the temperature of 30-37 degrees, high humidity, slightly acidic soil, the most likely to occur, the sudden high temperature after heavy rain, easily lead to disease epidemic. In the early stage of disease, the parietal lobe or the side lobe
