Problems solved by technology

[0008] The above methods all increase the zinc content in rice by applying zinc-rich chemical reagents, which are easy to affect the field environment, are not environmentally friendly, and are not suitable for the promotion and development of safe and nutritious green agriculture; The increase of zinc content, but it is unable to achieve pesticide-free or pesticide reduction at the same time

Embodiment 1

[0040] This embodiment was tested in Fuyang, Hangzhou, Zhejiang in the summer and autumn of 2016. The specific test contents are as follows:

[0041] (1) Select Yudao No.1, a rice variety with tall plant type, lodging resistance and suitable for deep water planting. In mid-May, use ordinary clay rich in organic matter as the substrate, use a nutrient bowl with a diameter of 10 cm to raise seedlings, and sow 2 grains of buds per bowl. After sowing, water thoroughly, keep the bed soil moist before 2 leaves and 1 heart, and then keep the state of "see dry and see wet, water it thoroughly", and form a developed and strong root system before transplanting.

[0042] (2) When the seedling grows to 6 leaves and 40cm, adopt 60cm×60cm, one clump and one pot density for transplanting, and the water level is 25cm when transplanting.

[0043] (3) Increase the water level step by step according to the plant height of the rice, and strictly irrigate the whole process so as not to submerge t...

Embodiment 2

[0055] This example was tested in Jiashan, Jiaxing, Zhejiang in the summer and autumn of 2017, and the whole deep-water cultivation method of symbiosis with freshwater shrimp was adopted. The specific content is as follows:

[0056] (1) Select the rice variety Zhedao No. 1 with tall plant type, lodging resistance and suitable for deep water planting. In late May, the common clay rich in organic matter was used as the substrate, and a nutrient bowl with a diameter of 10 cm was used to raise seedlings, and 3 grains of buds were sown in each bowl. After sowing, water thoroughly, keep the bed soil moist before 2 leaves and 1 heart, and then keep the state of "see dry and see wet, water it thoroughly", and form a developed and strong root system before transplanting.

[0057] (2) When the seedlings are basically grown to 7 leaves and 50cm, the seedlings are transplanted in a thin-density manner, and the water level is controlled below 30cm when transplanting. About one week after t...

Abstract

The invention discloses a cultivating method of green high-zinc rice. The method includes the following steps that a rice variety which has the plant height being larger than or equal to 150 cm in themature period and the plant height reaching up to 60 cm or above before jointing, is resistant to lodging, and has rice stem joints capable of forming water roots is selected, sowing and rice seedling raising are carried out, and rice seedlings are obtained; the rice seedlings are transplanted into a field, with the condition that plant newly-growing interior leaves are not submerged as the standard, whole-process deep water irrigation cultivation is carried out, no pesticide is applied in the cultivating process till the mature period, and the green high-zinc rice is harvested. The rice variety suitable for deep water planting is adopted, cultivation is carried out in a whole-process deep water irrigation mode, by means of the method, under the condition that the pesticide is not applied, rice plant diseases and pests, especially diseases caused by rice blast and lepidoptera pests are effectively controlled, the problem of pesticide residues is avoided, the content of zinc in rice grains is remarkably increased while the yield can be guaranteed, and then the green high-zinc nutritional rice is obtained.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to a cultivation method of green high-zinc rice. Background technique [0002] According to the "green" development concept, the double reduction plan of "weight loss and drug reduction" in agricultural production has become the will of the state and a key research and development project in my country; at the same time, food safety has increasingly become the focus of public attention. In recent years, rice blast, two migratory pests rice planthopper and rice stem borer have frequently broken out in my country, which has a significant impact on rice yield, hygiene and safety quality. Therefore, the development of environmentally friendly production of rice will help promote the development of safe and green agriculture. [0003] In addition to the disease and insect resistance characteristics of rice varieties themselves, appropriate cultivation techniques are also an imp...
