How to transplant autumn-crop tomatoes? A quick look at the latest precautions

Tomatoes are one of people's favorite vegetables. With the development of growing techniques, the area planted with tomatoes has grown wider and wider, and the technical requirements for growing them have become higher and higher. August to September is the transplanting period for autumn-crop tomatoes. So what precautions should be taken when transplanting autumn-crop tomatoes? Follow the editor and take a look.

1. Before transplanting

Before transplanting autumn-crop tomatoes, do a good job of disinfecting the greenhouse, apply base fertilizer reasonably, and after the previous crop is harvested, promptly clean up the field and disinfect the greenhouse. If time and conditions allow, methods such as high-temperature greenhouse sealing and methyl bromide fumigation can be used to disinfect the greenhouse; if time is tight, soil disinfection can be combined with land preparation and fertilization. Base fertilizer must be fully decomposed before it is applied. If there is no time, a rapid decomposition method using active bacteria can be used: mix organic fertilizer fermentation bacteria with water and spray it evenly on the farmyard manure. This not only allows the farmyard manure to decompose, but also helps eliminate odors.

2. At transplanting

When autumn-crop tomatoes are transplanted on schedule, it is a hot and rainy season, and it is also a period when soil-borne diseases such as stem base rot, Phytophthora root rot, and bacterial wilt occur more severely. Therefore, at transplanting, be sure to pay attention to the prevention of pests and diseases, following the principle of prevention first and combining prevention with control. At transplanting, chemicals such as carbendazim can be applied in the planting holes for prevention, and for root-knot nematodes, chemicals such as fosthiazate can be applied in the holes for prevention.

3. After transplanting

After transplanting, use the method of covering with two nets and one film to prevent high temperatures, pests, and rain. Shade nets should be used reasonably and should not be kept in place too long, so as to avoid tomatoes growing leggy due to insufficient light. Shade nets are generally used from 10 a.m. to 3 p.m. Ventilation is an extremely critical step in the hot season, so when using insect-proof nets, be sure to note that they are only suitable for use at the ventilation openings at the front of the greenhouse. In addition, strictly prevent rainwater from flooding the greenhouse and causing tomato root rot and dead plants. Therefore, when the greenhouse is flooded, promptly irrigate with well water, that is, irrigate the garden after waterlogging, to reduce the harm after rainwater floods the greenhouse, and hoe the soil at the right time to enhance soil aeration and promote root growth.
