一、设计由来在花生生产上由于开花不齐,初期花结的果实到收获前常因已过熟而变质;后期有效花又常因未能及时下针结果而成为粃果,造成不应有的减产。因此,如何采取栽培措施,控制下针结果速度,以提高花生产量。可是花生下针结果的快慢受以下条件影响:1.花生着生果针的茎节越近地表,果针越可及早入土,反之则迟。2.大气相对湿度为100％时,果针日伸长0.62—0.93厘米;如为57％时,则仅伸长0.02厘米。3.土壤含水量为22.61％时,果针经4天可至结实处;如为7.27％时,则需6天以上。我国许多花生产区,苗期气候偏旱,甚至已到盛花下针,雨季仍未到,这对控制其下针结果速度是个有利条件。生产实践证明,垄作的花生,果实结在隆起的土壤
First, the design origin In the peanut production due to uneven flowering, the early flowering fruit often before harvest due to over-ripening; the latter part of the effective and often due to failure to timely needle results become a fruit, resulting in should not have Cut production. Therefore, how to take cultivation measures to control the speed of needle results in order to improve the yield of peanuts. However, the speed of peanut needle under the influence of the following conditions: 1. Peanut with fruit needle stalk closer to the surface, the needle as soon as possible into the soil, on the contrary late. 2. Atmospheric relative humidity of 100%, fruit pin elongation 0.62-0.93 cm; 57%, it only stretched 0.02 cm. 3. When the soil water content is 22.61%, the fruit needles can reach the fruiting place after 4 days; if it is 7.27%, it takes 6 days or more. In many flower-producing areas of our country, the climatic drought at the seedling stage has even reached the top of the flowers and the rainy season has not yet reached. This is a favorable condition for controlling the speed of the needle-cutting results. Production practice has proved that ridge peanut, fruit knot in the uplift of the soil
