Key measures for rice planting in rice fields

Wheat in the paddy field can improve the utilization rate of land and temperature and light resources. It not only wins the initiative of the season, but also achieves high yield of rice and wheat, and can greatly simplify the agronomic process and reduce the labor intensity. The following key measures should be done in production.

The roots of the improved varieties of rice and wheat are lightly distributed and have strong tillering power. The varieties with strong anti-falling and anti-freezing ability and compact plant type should be selected.

The symbiotic period of the rice and wheat in the appropriate seasoning is 7 to 10 days. Generally, the suitable sowing period in southern Jiangsu is October 23-31, the Suzhong area is October 18-25, and the northern part of Jiangsu is October 10-20.

Appropriate amount of sowing wheat early morning sowing, but the wheat seedlings are vulnerable to damage during rice harvesting. Therefore, the seeding amount is required to be between constant sowing and precision sowing. Usually, the amount of seed is 6-8 kg per mu, using mist. Spray the machine to ensure even seeding.

Before the rice is collected, the fertilizer is applied with 15 kg of high-concentration compound fertilizer and 10 kg of urea per acre to achieve early growth and strong seedlings. 1 to 2 days before sowing or when planting with herbicide, mix urea or fine soil evenly when the rice leaves have no dew. After the medicine, keep the soil moist and the field can not accumulate water.

The planting wheat field without soil sealing treatment before and after sowing, after the rice is harvested and removed from the field, according to the grass age and grass phase, the appropriate stem and leaf treatment agent is used to remove the oil, paying attention to safe medication.

The anti-freeze-selling wheat field is not covered with seeds, and the wheat tiller and part of the roots are exposed on the soil surface, which is susceptible to drought, lack of fertilizer, low temperature and other adverse effects. Measures should be taken to cultivate strong seedlings. (1) Before harvesting rice, the wheat seedlings are covered with 1500-2000 kg of decomposed organic fertilizer or 150 kg of straw. (2) When the rice is harvested, it is kept at a height of 25 to 30 cm, which is a cover for the wheat seedlings. (3) Before the heart stage of the 3 seedlings of the wheat seedlings, the soil is evenly covered with 2 cm thick to improve the fertilizer efficiency and protect the roots, promote the roots under the tie, protect the wheat seedlings from overwintering safely, promote the occurrence of low tillers and secondary roots, and achieve the cultivation of strong seedlings and improvement. The purpose of stem stalk formation rate.

Fertilizer operation generally based on 5 to 10 kg of pure nitrogen per mu. During the wintering and returning periods, the amount of tillage occurs in the field where the tiller is insufficient or the yellowing is reduced. There are few roots in the lower layer of rice and wheat, and the soil fertility is poor in the later stage. It is easy to release premature aging. The jointing panicle fertilizer is generally applied 15 kg per mu, and is applied twice in the inverted 3 leaf stage and the flag leaf stage.
