First, the amount of straw should be sufficient, and with a good amount of strains, with 1 kg per 500 kg straw strain, 4000 ~ 5000 kg per mu straw.
Second, do not rush to apply pesticides when watering, especially to sterilize bactericides. Pesticides can be sprayed above the ground to prevent pests and diseases.
The third is not the first two months of chemical fertilizers, in order to avoid reducing strains, vaccine activity, late according to the conditions of fertility, appropriate topdressing a small amount of organic fertilizer and compound fertilizer (each time per acre soaking 7 to 10 days of soy flour , soybean cake and other organic fertilizer about 20 kg, about 10 kg compound fertilizer). Potassium dihydrogen phosphate can be sprayed on the leaves. Three years of continuous application can basically not use chemical fertilizers.
Fourth, scientific water is the key to applying a good reactor.
1. Built-in reactor first water. The built-in reactor is ready for pouring the first water, which is the starting water of the reactor, and the amount of water is large. The principle of mastering is to make the straw eat as much water as possible. On the 4th to 5th day after the first watering, the treated vaccine should be applied to the ridge and mixed with the soil to make holes.
2. Built-in reactor second water. That is, planting sapling water, watering can not be large, to pour water. On the day of colonization, each bowl of seedlings was poured with 1 bowl of water, and the high-temperature season was poured 3 times every 3 days. In the low-temperature season, a bowl of water was poured every 7 days. In the middle temperature season, a bowl of water was poured every 5 days. Do not cover the mulch after planting, wait for more than 10 days before the seedlings come back and cover the mulch, and drill in time.
3. The general conventional cultivation of pouring 3 times of water, use this technology only to water once, remember that watering can not be too much. In the case of watering the straw for the first time, it is usually watered after 70 to 90 days (according to the type of soil). Three days after watering, the air outlet should be magnified to remove moisture. Can use 45% chlorothalonil smoke agent fumigation, an acre of 250 grams.
4. Watering timing. The main points of watering in winter are: “Three Looks†(looking at the sky, seeing the land, seeing the seedlings) and “five cannot†(One cannot be poured in the morning, two cannot be poured in the evening, three can’t be poured into a little water, and four can’t be poured into the ground. , five can not be cooled during the pouring period). 5. In early spring, a big arch shed crop, the watering must be watered in sections, 10 ~ 15 meters, otherwise it will be watering too much, boring seedlings rot. 6. The application of drip irrigation water, water control is good, the best effect.
