Sufen No.11 and Sufen No.8 tomato cultivation points

I. Introduction

Sufen 11 is a new hybrid cultivar with high resistance to tomato yellow leaf curl virus disease. Plants grow indefinitely, and the first inflorescence is born in the 8th to 9th positions. Each inflorescence has 3 to 4 fruit sets, and it has a strong fruit setting ability. The fruit is round, pink and uniform in color. The fruit weight is about 200 grams, and the large fruit can reach 300 grams. The flesh is thick, resistant to storage and transportation, and the fruit flavor is good. High resistance to TYLCV, ToMV, resistance to leaf mold and blight. Suitable for all kinds of protective cultivation, especially suitable for the cultivation of tomato yellow leaf curl disease.

Soybean No. 8 middle-early hybrid, unlimited growth, high resistance to tomato tobacco mosaic virus disease, leaf mold. High round pink fruit, weighing 200-300 grams. Each fruit inflorescence is 4 to 5, the fruit size is uniform, the appearance is beautiful, there is no abnormal fruit, the quality is excellent, and it is resistant to storage and transportation.

Second, cultivation points

1. Sowing and planting in the middle and lower reaches of the Yangtze River, early-stage cultivation and open-field cultivation of spring greenhouses are generally planted from late November to the following year, and cold and hot bed planting can be used. The greenhouse was planted in mid-March, and the open field was planted after the frost break. Late autumn cultivation is usually planted in mid-July and planted in early August. Early spring cultivation of greenhouses or open field cultivation, colonization of 2800 ~ 3200 per acre; after the autumn delay cultivation, planting about 3000 per acre.

2. Scientific fertilization applies basal fertilizers before soil preparation, especially organic fertilizers. For each mu, 3000 to 4,000 kg of composted manure and 40 to 50 kg of phosphorus and potassium fertilizers are used to promote early plant growth and increase fruit setting rate; For fruit fertilizers, the application amount is greater than that of extracting seedlings; the results will be topped with top-dressing phosphorus and potash fertilizers or other trace elements for foliar spray application.

3. Plants were stalked with single stalks. After 3 to 4 spikes, 2 to 3 leaves were picked at the top of the inflorescence in order to promote early maturity and improve quality. During the growth process, the deformed flowers are removed as soon as possible, and excess fruits, deformed and too small fruits, and remaining flower buds on the same inflorescence are removed after the fruit is set.

4. Pay attention to the temperature during the flowering and fruiting period, and use plant growth regulators such as 2,4-D liquid or anti-dropping agents to prevent flowering and fruit settling and promote fruit enlargement.

5. Pest prevention and control shall adopt a strict crop rotation system and rotate with non-solanum crops. Areas with conditions may adopt paddy-upland rotation; use deep ditch sorghum to cover the mulch, cultivate age-appropriate seedlings, and improve resistance; strengthen field management, balance fertilization, increase Application of fully decomposed organic fertilizer, less application of chemical fertilizers; chemical control can be used 10% trisodium phosphate solution soaked for 10 minutes to kill the bacteria on the surface of the seed, with pyrethroid pesticides to control aphids, cotton bollworm, with antiviral 500 times solution or Swiss Poisonous mold 800 times liquid to prevent disease, spray once every 7 to 10 days.
