Key points of growing fruits in greenhouse
1. Facilitative cultivation
Very early-maturing, early-maturing and medium-maturing varieties should be selected to facilitate early listing, while delayed cultivation should choose late-maturing varieties or varieties that are easy to bear many times.
2. The dormant period is short
The varieties with short natural dormancy period, low cold demand and easy to break dormancy manually were selected for early or ultra-early protection production.
From the environmental point of view, the greenhouse facilities to promote the cultivation of fruit trees, the earlier the greenhouse time, the earlier the maturing time on the market, the higher the benefit. However, the time of withholding greenhouse in greenhouse cultivation is limited, and it is not infinitely in advance and at will. Because all deciduous fruit trees have the habit of natural dormancy, if the accumulation of low temperature is not enough, it can not reach the amount of cold needed by fruit trees, and without natural dormancy, even if the greenhouse is kept warm and suitable environmental conditions for growth and development are given, fruit trees will not sprout and blossom. Sometimes although they sprout, they often blossom irregularly, have a long production cycle and have a low fruit setting rate. Therefore, the cooling capacity is the primary basis for determining the time of withholding shed. To meet the chilling requirement of fruit trees and to buckle them through natural dormancy is the basis of successful cultivation in greenhouse facilities. Only in this way can fruit trees grow and develop normally in greenhouse facilities.
