Paddy field no-tillage autumn potato supernormal early-sowing planting method

Abstract

The invention provides a paddy field no-tillage autumn potato supernormal early-sowing planting method. The method comprises the steps that after previous crop rice seeds, water draining and filed drying are kept conducting in time until small cracks occur in a field, then in mid to late august according, 20-50 g small dormancy-broken whole potatoes are sown on the base of rice stubble according to the line spacing of 60 cm*20 cm, terminal buds are buried into the rice stubble, the damp environment of the paddy field is used for promoting the potato seedling germination during the period. After the rice is harvested, concentrated fertilization is conducted in time on the other side of the rice stubble where the potatoes are placed, and 40-60 kg compound fertilizer is applied per acre. After the fertilizer application, the line space between the germinated potatoes is covered with collected straw to wait for the potatoes to germinate and grow until harvest. According to the paddy field no-tillage autumn potato supernormal early-sowing planting method, the autumn potato planting time can be greatly advanced, the growing period is extended, and the problems that the potatoes sowing is too late after the rice is harvested, so that the potatoes suffer the late frost damage and the yield sharply decreases are solved.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and relates to a cultivation method for planting autumn potatoes with no-tillage and ultra-early sowing in paddy fields, prolonging the growth period and avoiding low temperature and frost damage. Background technique [0002] Potatoes are one of the main food crops in my country. Especially in recent years, it is difficult to increase the production of food crops such as rice, corn, and wheat, which have already had a high yield per unit area in recent years. The effect of increasing income is particularly prominent. In this context, vigorously developing the potato industry, increasing the yield per unit area and expanding the potato planting area has become an important way to increase grain production and income. However, it is unrealistic to expand the planting area in traditional grain planting areas and compete with other crops for water and land, thereby reducing the yield of other ...

Problems solved by technology

However, in many rice-producing areas, rice is harvested in mid-September, and autumn potatoes are planted after harvest. Generally, the seedlings do not emerge until around mid-October, and the temperature drops rapidly in mid-to-late November, and potatoes are in the tuber formation period. If it is too low, it will seriously affect the formation and expansion of potato tubers. After December, there may be frost damage, resulting in reduced production or no harvest. The risk is very high

In these areas, planting autumn potatoes in the sun after the rice is harvested will lead to the normal growth of the sown delayed-shadow potatoes, which are prone to frost damage in the later stage, resulting in a substantial reduction in potato production and bringing hidden dangers to farmers' stable production and income growth
