Problems solved by technology

However, improper fertilization can easily lead to fertilizer damage. For example, too much fertilizer will lead to an increase in ineffective tillers, premature closure, weakened resistance to insects, diseases, and lodging, late maturity due to greedy greens, and decreased seed setting rate and 1,000-grain weight, which will affect rice yield and quality; Partial application of nitrogen fertilizer, ignoring the combined application of phosphorus, potassium fertilizer and farmyard manure, affects the normal growth and development of plants
Improper use of regulators may over-inhibit, prone to phytotoxicity, affect the development of stems and ears, resulting in reduced yield or even no harvest

Embodiment 3

[0046] 1. Test object: rice (variety: Luyouxiang 104)

[0047] 2. Test time: from late March to late August

[0048] 3. Climate conditions: 20~40℃, wind speed 3-6, humidity 70~90%

[0049] 4. Test method: Spray the whole plant for pesticide application. After 7 days, apply the pesticide for the second time, both at around 10:00 in the morning. After 7 days and 14 days, carry out the first time and the second time to observe the safety of spraying medicine. According to "Pesticide Indoor Bioassay Test Guidelines NY / T2061.2-2011" (two standards), 5 samples are taken in each plot, and 4 plants are randomly sampled at each point, and 20 plants are investigated for their plant height, ear length, seed setting rate, and The thousand-grain weight, starch content, protein content and other indicators were measured during the harvest period, and the results are shown in Table 3 and Table 4.

[0050] Among them, the whole growth period of the rice (Luyouxiang 104) is 143.5 days on av...

Abstract

The invention discloses a composition for plumping seeds and increasing yield, and a preparation and an application of the composition. The composition is prepared from naphthylacetic acid and benzylaminopurine in a weight ratio of (1.0 to 10.0):1. The composition has effects of enhancing tillering of crops and plumping seeds and increasing yield of crops. The preparation, by selecting and matching with solvents, auxiliaries or carriers, has long-term stability, so that the application effect of the effective components naphthylacetic acid and benzylaminopurine is improved.

Description

technical field [0001] The invention relates to the technical field of plant growth regulators, in particular to a composition, preparation and application for strengthening seeds and increasing production. Background technique [0002] The growth and development of food crops are divided into vegetative growth and reproductive growth. Different growth periods are interrelated and restrictive. One of the principles of high-yield cultivation is to coordinate the relationship between the vegetative growth period and the reproductive growth period. The peak period is the critical period for fruiting. The population with balanced nutritional status and high light efficiency is of great significance to increase the seed setting rate and grain weight. The heading and fruiting period requires a lot of water and mineral nutrients; at the same time, it is necessary to enhance root activity and prolong the functional period of stems and leaves. [0003] Grain yield is mainly composed ...
