A Detailed Explanation of the Key Techniques for High-Yield Tomato Cultivation

The yield of tomatoes is also related to a certain extent to cultivation techniques. With good field management, tomato yields will increase accordingly. So what are the techniques for high-yield tomato cultivation?

1. High-yield tomato cultivation techniques

1. Seed selection: Choose excellent varieties with good resistance to pests and diseases and tolerance to heat and cold. Qiangfeng, Jiafen No. 10, Zhongshu No. 4, and Jinfen 65 are all good varieties.

Before sowing, the seeds also need to be soaked in an appropriate amount of trisodium phosphate solution. The specific method is as follows: soak the seeds in clean water for 3 h, wash them clean, place them in a 10% sodium phosphate solution by mass fraction for 30 min, then rinse with clean water, air-dry the seeds for 20 h, and then sow.

2. Planting: Choose loose soil with good drainage for planting. Generally, the row spacing is about 60 cm and the plant spacing is about 30 cm. In addition to applying a heavy base fertilizer, apply 1 seedling-promoting fertilizer after the seedlings recover.

Per mu, apply 250-500 kg of decomposed manure in holes, or 10-12.5 kg of potassium sulfate, and then water heavily once to lower the temperature and help the seedlings recover.

Planting is generally carried out on sunny, windless days.

3. Field management: Water and fertilize reasonably and carry out pest and disease control.

Among these, diseases are further divided into late blight, viral disease, bacterial wilt, and others. The control methods for different pests and diseases are also different, and chemicals need to be used according to the specific situation.

2. Control methods for tomato pests and diseases

1. Late blight: Carry out crop rotation with non-solanaceous crops for more than 3 years; at the early stage of the disease, begin spraying with 72% cymoxanil mancozeb wettable powder diluted 800-1000 times, spraying once every 7-10 days for 3-4 consecutive times; remove diseased plant residues, promptly remove diseased leaves and fruits during the disease season and bury them deeply, and promptly clear away diseased residues after harvest.

2. Viral disease: Choose disease-resistant hybrid varieties; manage scientifically, cultivate strong seedlings, increase the application of phosphorus and potassium fertilizers, and promote robust plant growth to improve disease resistance; use disease-free seeds and disinfect the seeds before sowing; before the disease occurs or at the early stage of its appearance, you may choose 40% Kedubao soluble powder 1000-fold solution, spraying once every 7-10 days for 2-3 consecutive times.

3. Bacterial wilt: In severely affected areas and fields, carry out crop rotation, preferably paddy-upland rotation with rice; start strengthening inspections at the early fruit stage. Once diseased plants are found, pull them out immediately, collect and burn them, and drench the diseased holes and nearby plants with 77% Keshade suspension concentrate 800-fold solution, or Saoxi 800-fold solution, more than 2 times, once every 7-10 days, with closer intervals first and wider intervals later, drenching thoroughly and sufficiently (200-500 milliliters per plant or more).
