Problems solved by technology

[0004] Pushing it into rivers or ponds will pollute water sources and cause harm to aquatic organisms
[0005] The rice fields are farmed on a household basis, relatively scattered, and inconvenient to collect and transport. They are used to make handicrafts and biofuels, and a lot of manpower, material resources and time are required for collection and transportation.
[0006] Most of the migrant workers entered the cities, and a large number of rural labor force was lost. Due to the lack of young labor force, farmers farmed only to ensure rations. Coupled with the progress of breeding, the grain yield was high. Many farmers planted rice for one season, or did not plant it at all, resulting in a lot of idle time. fields, wasting land productivity

Embodiment 1

[0042] Embodiment 1, it comprises the following steps:

[0043] (1) Harvesting one-season rice: Sowing one-season rice from late March to late April, transplanting one-season rice seedlings from early April to mid-May, implementing field moist management to cultivate one-season rice, and harvesting one-season rice in early August.

[0044] (2) Cultivation of ratooning rice: The ratooning rice is cultivated after the first season of rice is harvested, and the ratooning rice is harvested from mid-October to early November.

[0045] (3) Cultivation of wild fungi: After the ratooning rice is harvested, the straw after harvesting the rice is laid on the field on the spot, and wild fungi are planted on the straw. The propagation of the wild fungus will accelerate the decay of the straw. Further rot, become organic fertilizer, enhance soil fertility, improve the soil quality of the field, and prepare for the next year's rice planting.

Embodiment 2

[0046] Embodiment 2, the preferred growth and development period of one-crop rice is the rice variety of 128-135 days, and the mixed fertilizer comprising quicklime and plant ash is sprinkled at the tillering stage, and the pH value of the soil is adjusted to be greater than 6 or less than 7.2, so as to reduce the resistance of the seedlings to cadmium. Absorption: Spray selenium (Se)-containing foliar fertilizers at the initial earing stage to increase the absorption of selenium by seedlings, especially young ears, so as to produce selenium-enriched rice and inhibit the absorption of cadmium by rice. All the other are with embodiment 1.

Embodiment 3

[0047] Embodiment 3, the specific steps of cultivating ratooned rice include:

[0048] (1) Planting one-season rice: Harvest the first-season rice in early August, apply urea 10 days before the first-season rice harvest, and the amount of urea per mu is 10-25 kg. Break into 3-5cm rice segments and return to the field. The rice segments are covered on the field soil, which can prevent the growth of weeds and form organic fertilizer.

[0049] (2) Clean up the rice stubble to avoid covering the rice stubble with the returned rice section.

[0050] (3) Apply urea 10 days after harvesting the first-season rice, and the amount of urea per mu is 5-10 kg.

[0051] (4) Spray 902 gibberellin, 2g / mu, about one week after the regenerated seedlings emerge, to stimulate the growth of leaves and buds and increase the yield.

[0052] (5) Sprinkle mixed fertilizer including quicklime and plant ash during the tillering stage, and adjust the pH value of the soil to be greater than 6 but less t...

Abstract

The invention discloses an efficient farmland utilization method for cultivating single-season rice, ratoon rice and wild fungi and mainly solves the technical problem that existing farmland utilization rate is not high, waste straw treatment methods are not environmentally friendly, the economic benefits are not high and the like. The technical scheme is characterized as follows: by cultivating the ratoon rice, labor force output is reduced while the grain yield is guaranteed, first rice straw is crushed and returned to the field, growing of weeds in the rice field can be avoided, the field can be fertilized, cadmium reduction and selenium enrichment measures are taken, low-cadmium and selenium-rich rice is produced, straw after harvesting of the ratoon rice is laid on the field, the wildfungi are planted on the straw, propagation of the wild fungi can accelerate rotting of the straw, after the wild fungi are harvested, the straw further rots to form organic fertilizer, the soil fertility is enhanced, and the soil property of the field is improved.

Description

technical field [0001] The invention relates to a farmland efficient utilization method for cultivating one-crop rice, ratooning rice and wild mushrooms. Background technique [0002] Currently, rice straw is disposed of in the following ways: incineration, pushing into rivers or ponds, making handicrafts and biofuel. [0003] Rice straw contains a large amount of carbon elements. When it is incompletely burned, it will produce toxic gases such as carbon monoxide and a large amount of carbon dioxide. A large amount of burning will intensify the greenhouse effect, resulting in a large change in the total amount of gas components, which will make the climate abnormal. , the global temperature is rising, and at the same time, a lot of dust will be produced after burning rice straw, forming dust pollution. Although the burned ashes can be used as potassium fertilizer, the fertilizer efficiency is too low. Therefore, incineration is an unsuitable rice straw treatment method in t...
