Problems solved by technology

[0009] With the development of the times and the progress of society, people pay more and more attention to the construction of ecological civilization. It has become a consensus to accurately input nutrients and improve nutrient utilization efficiency in agricultural production. Therefore, aiming at blind fertilization, single fertilization, and excessive fertilization The problem of unreasonable use of fertilizers, urgently needs a nutrient precision management technology

Embodiment 1

[0067] A method for precise management of scallions nutrients, comprising the following steps:

[0068] 1) Determination of yield response coefficient of scallion: The yield response coefficient of scallion on soil with different basic nutrient supply levels is as follows:

[0069]

[0070] Soil basic nutrient supply grades are divided into three grades: high, medium and low, and the grades are determined according to soil characteristics and history of organic fertilizer application.

[0071] The soil nitrogen nutrient supply level is judged according to the soil characteristics as follows:

[0072] Low: sandy soil (regardless of soil color) or reddish / yellowish loam or clay;

[0073] Medium: gray / brown loam or clay;

[0074] High: High organic matter content and black loam or clay;

[0075] The high organic matter content refers to the soil organic matter content>15g / kg; if a large amount of organic fertilizer is applied (2t / ha or more poultry manure is applied every s...

[0101] Experimental Example 1: Field Test Verification

[0102] The test was carried out in Zaoyuan Town, Zhangqiu District, Jinan City, Shandong Province from June to November 2017, and the test sites were located in Qingyuan Village and Wanxin Village. Before the scallions are planted, the planting situation of each test site plot is investigated, and the target yield and soil basic nutrient supply level are determined according to the investigation results, and the yield response and nitrogen are calculated by the scallion nutrient precision management method (NE) of the embodiment of the present invention 1. The amount of phosphorus and potassium nutrients (see Table 1), and the local soil testing formula fertilization (OPTS) and farmers' practice (FP) treatments were set as controls. A total of 3 treatments, the area of ​​the plot is 100m 2 Above, without repetition, each fertilization treatment scheme is shown in Table 1 below:

[0103] Table 1 Fertilization schemes of...

Abstract

The invention relates to a green Chinese onion nutrient precision management method which includes the steps: 1) determining green Chinese onion yield response coefficient; 2) determining the target yield of a planting plot according to local past green Chinese onion yield; 3) determining yield response (t / ha)=the yield response coefficient*the target yield (t / ha); 4) calculating optimal green Chinese onion nutrient quantity according to the target yield, yield response and agricultural efficiency; 5) determining a fertilization management method according to soil nutrient supply grades and the optimal green Chinese onion nutrient quantity. Nutrient input quantity is precisely calculated according to the target yield of green Chinese onions, a nutrient management method is refined according to production conditions, nutrient precision management for green Chinese onion production can be realized, improper nutrient input and application are avoided, the yield and the quality of the green Chinese onions are improved, the income of farmers is increased, and the yield and efficiency are increased.

Description

technical field [0001] The invention relates to a precise nutrient management method for scallions, belonging to the technical field of agricultural cultivation. Background technique [0002] Scallions have high nutritional value (containing allicin, diallyl sulfide, niacin, stearic acid, vitamins, etc.) and medical value (can treat headache, fever, stomach pain, indigestion, sore tumor, red and white dysentery, It is a very common spice seasoning in people's daily life, and it plays an important role in cooking. It is not only an important annual balanced supply of vegetables in China, but also one of the important vegetables for export to earn foreign exchange. China is the main country for the cultivation of scallions, which are cultivated from the Yellow River Basin to all parts of the Northeast, with an annual cultivation area of ​​more than 15 million mu, and scallions have become a pillar industry in many places. [0003] The growth of green onions has strong adapta...
