I. Responding to autumn tiger temperature (priority)
The seeding is avoided by midday and is chosen for morning and evening planting; the seed is covered with straw and the sunnet is wet and cooled to prevent high temperatures from burning。
2. At continuous high temperatures, fragrances and spinach are easy to fall asleep and can be seeded with low-temperate seedlings。
3. Water-watering techniques: early and late watering, with a ban on heavy-water flooding at noon; small-water irrigation to prevent soil from drying and wetting。
Ii. Control the seeding time and prevent pre-smoking
1. Cabbage and carrots cannot sow too early, and persistent high temperatures are prone to dry-crazy hearts and screeching; nor are they too late for later light to be reduced and their heads to be small。
2. Vegetables are sowed in batches, with the wrong harvest period, and one-time large-scale sowing can easily concentrate on mature and rotten vegetables。
Elements of soil management
1. Infertile soil, pests, weeding before seeding, decomposed farmers ' fats or compound bottoms; no direct application of fresh, raw manure, easily burning roots and breeding ground worms。
2. During the rainy season, drains are well prepared and rain is increasing in the autumn, and water accumulation is highly likely to result in rotten roots and seeds。
Early prevention of pests and diseases
1. High temperature and humidity: rheumatism, leaching, aphids, slashed night moths, large cabbage and radish are the worst affected areas. Physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physico-physytic (physyroidnet)。
2. Frost and morbid diseases after rain, with a focus on the prevention of cabbage after planting。
V. Varieties selection
1. Prioritize the selection of heat-resistant, disease-resistant, autumn-resistant varieties, rather than spring-resistant varieties。
2. Autumn beans and cucumbers choose varieties that are resistant to high temperatures and are not prone to premature decay。
Child breeding and plant migration
1. Celery, cabbage and cabbage recommend the planting of seedlings, which are broadcast on the air, and the selection of shades or evenings, which are followed by two to three consecutive days to cover the sun。
2. The planting of seedlings should not be too deep in order to avoid decay。
A simple north-south distinction reminder
(a) north: hold on to the seeds, reserve enough growth cycles to guard against early frost
Sichuan/yang river basin: the focus is on fighting the high temperature of tigers in the autumn and drought + short-term heavy rains
South china: postponed cabbage and radish seeding can easily fail to sustain high temperatures。
Viii. The principle of fertilization
Nitrogen is not suitable for overweight during thin periods of seeding, and phosphate fertilizer is applied in the mid to late stages of root vegetables (radish, potatoes) to promote root expansion。
